[0002] In the current fields of mining, construction, and large-scale equipment maintenance, hydraulic column pullers, as important auxiliary equipment, are widely used in the dismantling of structures such as pillars and steel frames. Existing hydraulic column pullers are mostly fixed structures, bulky, inconvenient to transport and store, and have a single function, mainly limited to vertical extraction operations. In addition, these devices have poor adaptability in complex environments (such as narrow spaces and highly restricted areas), lack operational flexibility, and increase the difficulty and cost of operations. More importantly, existing equipment often lacks an effective folding mechanism and cannot quickly adjust its shape according to actual needs, which limits its scope of application and efficiency; therefore, we propose a multifunctional hydraulic column puller to solve this problem.

Two guide rods 11 are fixedly connected to the inner side of the movable plate 9. One end of the output shaft of the third motor 8 is transmission-connected to one end of the bidirectional threaded rod 10 through a third coupling. The outer side of the bidirectional threaded rod 10 is threadedly connected to two clamping blocks 12, and the two clamping blocks 12 are slidably connected to the outer sides of the two guide rods 11; start the first motor 2 installed on the top of the vehicle body 1, when the first motor 2 rotates, the rotating plate 5 rotates with the first motor 2 as the axis, when the first motor 2 rotates, the rotating plate 5 is driven to rotate so that the top surface of the rotating plate 5 is perpendicular to the top surface of the vehicle body 1, after completing the installation of the device, the staff can start the second motor 7, when the second motor 7 rotates, the second motor 7 drives the screw rod 6 at one end of the output shaft to rotate, when the screw rod 6 rotates, the screw rod 6 drives the outer movable plate 9 along the two guide When the second moving plate 13 is moved in the direction of the second moving plate 13, and when it moves to a suitable position, the third motor 8 installed on one side of the moving plate 9 is started to rotate. When the third motor 8 rotates, the bidirectional threaded rod 10 is driven to rotate through the coupling of the output shaft. When the bidirectional threaded rod 10 rotates, the bidirectional threaded rod 10 drives the two outer threaded clamping blocks 12 to move toward each other, thereby wrapping the outer side of the pillar or structural member. The shape of the clamping block 12 can be changed according to actual conditions, and holes can also be punched on the outer side of the clamping block 12, and chains can be installed to help the clamping block 12 to limit the column pulling; when the device is not used, the first motor 2 of the device drives the rotating plate 5 to rotate, so that it is folded on the top of the vehicle body 1 for placement.

[0023] The implementation principle of a multifunctional hydraulic column pulling machine in the embodiment of the utility model is as follows: when the staff uses this device, the staff first moves the device to a suitable position. When it is necessary to pull out the pillar or structural member, the staff starts the first motor 2 installed on the top of the vehicle body 1. When the first motor 2 rotates, the rotating plate 5 rotates with the first motor 2 as the axis. When the first motor 2 rotates, it drives the rotating plate 5 to rotate so that the top surface of the rotating plate 5 is perpendicular to the top surface of the vehicle body 1. After completing the installation of the device, the staff can start the second motor 7. When the second motor 7 rotates, the second motor 7 drives the screw rod 6 at one end of the output shaft to rotate.

The shape of the clamping block 12 can be changed according to actual conditions, and holes can also be punched on the outer side of the clamping block 12, and chains can be installed to help the clamping block 12 to limit the column pulling; when the device is not used, the first motor 2 of the device drives the rotating plate 5 to rotate, so that it is folded on the top of the vehicle body 1 for placement. When the object needs to be transported, the staff places the device on the inner side of the two clamping blocks 12, and starts the third motor 8 to drive the two clamping blocks 12 to clamp the inner object to prevent the object from shaking during transportation and increase the stability of the device during movement;

[0024] When a pillar or structural member is to be removed, since the pillar or structural member installed on the front side is heavier, the staff rotates the limit block 3 to the front side of the vehicle body 1 and limits it through an external limit column to increase the stability of the device when the pillar or structural member is to be removed.
