Made from concrete and reinforced with steel or wire, it undergoes a variety of processing steps. Cement utility poles are a vital component of modern power and telecommunication networks, their durability making them an indispensable part of urban and rural infrastructure.
[0003] During the production process of cement utility poles, the steel cage needs to be transferred to the mold used to make the utility pole by the overhead crane, which drives the sling holding the steel cage. However, utility pole products have various specifications, which correspond to various lengths of steel cages. Therefore, the sling for lifting the steel cage needs to be adjusted accordingly during the process.
[0004] In view of this, in order to improve the versatility of the spreader and increase the convenience of adjustment of the spreader, this new spreader was developed. Utility Model Content

[0021] Figure 2 This is a schematic diagram of the connector structure of the present utility model;
[0022] Figure 3 This is a front view of the connector of the present invention. DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0024] See Figure 1-3 , discloses a utility pole steel cage hoist, which is used to improve the versatility of the hoist and enhance the convenience of adjusting the hoist.
[0025] In the embodiment of the present disclosure, Figure 1As shown, the utility pole reinforcement cage hanger includes a straight-extending support beam 100, such as an I-beam, a square tube, etc., a lifting ring 200 is provided on the upper side of the support beam 100, and a lifting hook 300 is provided on the lower side. The lifting ring 200 and the lifting hook 300 are connected to the support beam 100 through a connector 400; the upper and lower sides of the support beam 100 are both provided with limiting holes 101 arranged in a straight line along the length direction; Figure 2 As shown, the connector 400 includes a mounting base 401, the mounting base 401 is provided with a U-shaped mounting groove 402, a mounting shaft 403 is provided on the opening direction side of the mounting groove 402, the length direction of the mounting shaft 403 is parallel to the width direction of the mounting groove 402, a connecting base 404 is hinged on the mounting shaft 403, the connecting base 404 is provided with a connecting hole 405 on the side opposite to the opening direction of the mounting groove 402 and away from the mounting shaft 403, a lifting ring 200 is provided on the connecting hole 405, and the connecting base 404 is provided with a side opposite to the length direction of the mounting groove 402 and away from the mounting shaft 403 in the direction of the bottom of the mounting groove 402. A side-raised limit pin 406; the connector 400 is arranged on the support beam 100, so that the support beam 100 is inserted into the installation groove 402. When the lifting ring 200 is pulled away from the support beam 100, the limit pin 406 can be inserted into the limit hole 101; a plurality of connectors 400 are arranged at intervals on the support beam 100, two of which are arranged on the support beam 100 with the connecting holes 405 facing upward, and the remaining connectors 400 are arranged on the support beam 100 with the connecting holes 405 facing downward, and a hook 300 is arranged on the connector 400 with the connecting hole 405 facing downward, and the hook 300 is arranged on the lifting ring 200.
[0026] When the utility pole reinforcement cage sling of the present invention is used, the hooks below the overhead crane can be used to respectively hook the lifting rings 200 of the connectors 400 with the connection holes 405 facing upwards. Then the hooks 300 provided on the remaining connectors 400 can be used to hook the reinforcement cage to transport the reinforcement cage.
[0027] When the telegraph pole reinforcement cage hoist needs to be adjusted, the spacing between the connectors 400 with hooks 300 is mainly adjusted according to the different lengths of the reinforcement cage, so that the hooks can be dispersed in the length direction of the reinforcement cage, applying a more evenly distributed force to the lifted reinforcement cage.
[0028] To adjust the position of the connector 400, simply reduce the force applied to the connection hole 405 away from the support beam 100 and swing the connection base 404 to remove the stop pin 406 from the stop hole 101. This allows the connector 400 to slide along the length of the support beam 100. To restrict the connector 400 to a certain position on the support beam 100, apply tension to the lifting ring 200 away from the support beam 100 to insert the stop pin 406 into the stop hole 101.
[0029] In order to facilitate the movement and operation of the limiting pin 406 , the limiting hole 101 is a long hole whose length direction is parallel to the length direction of the support beam 100 .
[0030] There are four connectors 400 with the connection holes 405 facing downwards, such as Figure 3 As shown, two of the hooks are located between the two connectors 400 with their connection holes 405 facing upward, and the other two are located outside the two connectors 400 with their connection holes 405 facing upward, one at each end of the support beam 100. The four hooks are used to hook onto the ends and middle of the steel cage, ensuring uniform force during suspension and preventing deformation during movement.
[0031] like Figure 3 As shown, the connecting hole 405 is arranged on the side of the installation shaft 403 away from the limiting pin 406. The installation shaft 403 is arranged on the central axis of the bottom length direction of the installation groove 402.
[0032] Furthermore, to facilitate the hooking of the steel cage, a downwardly hanging rope 500 is provided on the lifting ring 200 of the connector 400 with the connection hole 405 facing downward, and a hook 300 is provided at the lower end of the lifting rope 500. Furthermore, a hook 300 is provided at each end of the lifting rope 500, one of which is hooked on the lifting ring 200 to allow the lifting rope 500 to hang naturally.
[0033] Furthermore, if Figure 2 and Figure 3 As shown, a residual shaft 408 can also be provided on the mounting groove 402, and a residual hole 407 is provided on the connecting seat 404. The residual hole 407 has a larger diameter, and the residual shaft 408 is passed through to retain a certain swing space for the connecting seat 404. Compared with the position of the mounting shaft 403, the residual shaft 408 is farther away from the bottom of the mounting groove 402, and does not affect the swing of the connecting seat 404 within a certain range, but can prevent the mounting shaft 403 from falling off and causing accidents.
[0034] In summary, the utility pole steel cage crane can be used to lift steel cages of different lengths, has good versatility, and is easy to adjust.
[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
