Description

A walking cable pay-off platform

technical field

The invention relates to the technical field of cable laying tools, in particular to a walking cable laying platform.

Background technique

The cable laying construction requires that the cable shaft be transported to the site, and the closer the cable shaft is to the starting point of the cable laying position, the more convenient the construction is, and it is beneficial to speed up the construction progress. Due to the large volume, weight and tonnage of the cable shaft, the cable shaft must first be transported to the site by a crane, then the cable will be wound out by hand, and then the cable head will be grabbed and dragged into the laying site. Due to the different construction environments, the location and position of the cable laying are complicated. In a narrow space, the crane is not easy to enter the best position, so the position of the cable shaft is not ideal. It is often necessary for the construction personnel to release the cable end from the cable shaft. Pull the shoulder to drag the cable and complete the cable laying work. The cable pay-off platform in the prior art is large in size and heavy in weight, and must be carried by a large crane. The disadvantages of this construction method are: it requires a lot of manpower, consumes a lot of money, and sometimes it cannot be operated normally due to the influence of the construction environment, which especially affects the construction progress.

In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a walking cable pay-off platform, including two identical car bodies, each car body includes a car box frame, two wheels and two supports; The wheels are installed in the carriage frame through the central shaft equipped with bearings, and the lower end surface of the carriage frame is higher than the lower end of the wheels; The wheels are higher than the ground, and the supports can be folded upward to make the wheels touch the ground, and each support has a rolling slope of the cable shaft.

The further improvement of the present invention is: it also includes auxiliary wheels installed in the carriage frame, the auxiliary wheels are located between the wheels, the auxiliary wheels are movably connected with the carriage frame through the central shaft equipped with bearings, and the upper ends of the auxiliary wheels are connected to the wheels. The upper ends are on the same horizontal line. Rectangular grooves are arranged on the upper end surfaces of the front and rear side walls of the carriage frame between the two wheels, and the two ends of the central axis of the auxiliary wheels are rectangular bodies, and the two ends of the central axis of the auxiliary wheels are stuck in the rectangular grooves . A connecting frame is also included, and the connecting frame is installed between two vehicle bodies arranged side by side. The connecting frame is provided with a mechanism for adjusting the distance between the two car bodies. Annular grooves are provided on the outer peripheral surface of the wheel and the auxiliary wheel.

The beneficial effects produced by adopting the above-mentioned technical solution are: the support of the present invention is folded upwards so that the wheels touch the ground, and the two car bodies can be dragged on the ground to walk near the cable shaft; the support is folded downwards so that the wheels are higher than the ground, The connecting frame positions the distance between the two car bodies, the cable shaft can be directly pushed onto the two car bodies, and the cable can be released by turning the cable shaft, which can speed up the construction progress. The construction of the invention saves the cost of a large crane, is convenient and quick to use, is convenient to fold and store, can save manpower and material resources, speed up the construction progress, and improve the construction efficiency.

detailed description

Embodiment 1: A walking cable pay-off platform includes two identical car bodies, each car body includes a car box frame 8, two wheels 3 and two supports 2; the wheels 3 are equipped with bearings The central axis of the trunk frame 8 is installed in the trunk frame 8, and the lower end surface of the trunk frame 8 is higher than the lower end of the wheel 3; The wheels 3 are higher than the ground, and the support 2 can be folded upward to make the wheels 3 contact the ground. Each support 2 has a cable shaft rolling slope 1 . Also comprise the auxiliary wheel 5 that is installed in the carriage frame 8, described auxiliary wheel 5 is positioned between the wheels 3, the auxiliary wheel 5 is movably connected with the carriage frame 8 by the center axis that bearing is housed, the upper end of the auxiliary wheel 5 and the wheel 3 The upper ends are on the same horizontal line. Rectangular grooves 6 are arranged on the front and rear side walls of the carriage frame 8 between the two wheels 3. The two ends of the central axis of the auxiliary wheel 5 are rectangular bodies 7, and the two ends of the central axis of the auxiliary wheel 5 are rectangular. Clamped in the rectangular groove 6. It also includes a connecting frame 9, which is installed between two vehicle bodies arranged side by side. The connecting frame 9 is provided with a mechanism for adjusting the distance between the two car bodies. Annular grooves are provided on the peripheral surface of the wheel 3 and the peripheral surface of the auxiliary wheel 5 .

How to use: first turn the cable shaft by hand and push it to the place closest to the construction site; (see Figure 6) Secondly, when the support 2 is folded up, the wheel 3 touches the ground, hook the connecting frame 9 with an iron hook, and put the two Two car bodies side by side are pulled near the cable; (see Fig. 1) the carriage frame 8 is erected by folding the support 2 downwards so that the wheels 3 are higher than the ground; (see Fig. 3) again, the large cable shaft 12 is passed through the cable shaft The rolling ramp 1 is pushed between the two wheels 3, at which point the large cable shaft 12 can be easily turned to release the cables. Wooden wedges 13 can also be used to replace the cable shaft rolling slope 1, which not only facilitates the protection of the cable shaft, but also facilitates the folding of the support 2. (See Figure 5) If it is a medium-sized cable shaft 14, the two ends of the central axis of the auxiliary wheel 5 can be stuck in the rectangular groove 6, so that the medium-sized cable shaft 14 is erected between the auxiliary wheel 5 and a wheel 3, and the spare rectangular Groove 4 can adapt to the use of cable shafts with different diameters. Connecting frame 9 can pass two car bodies with two axles, fixes with nut respectively, makes the spacing of two car bodies adapt to cable shaft length, conveniently pulls two car bodies simultaneously. The mechanism for adjusting the distance between the two car bodies can use the distance-adjusting nut 11. (See Figure 2) Set the distance-adjusting nut 11 on the connecting frame 9 between the two car bodies. By adjusting the distance between the two car bodies, the length can be adjusted. Different cable shafts are used. The present invention can complete the cable releasing work by two people's operation.
