[0025] like Figures 1-2 As shown, a lifting clamp of this utility model includes two clamping parts 1 and a lifting part 2. The two clamping parts 1 are rotatably connected, and two connecting pieces 3 are provided between the two clamping parts 1. One end of the two connecting pieces 3 is rotatably connected to the clamping parts 1 respectively, and the other end of the two connecting pieces 3 is rotatably connected to the lifting part 2. When the lifting part 2 is lifted, the connecting pieces 3 drive the two clamping parts 1 to close.

[0026] When transporting the woven bag containing the dust rod, the clamp is placed above the woven bag, the woven bag is located between the two clamping pieces 1, the lifting part 2 is lifted up, at this time the lifting part 2 moves upward relative to the clamping piece 1, the angle between the two connecting plates 3 decreases, and the two clamping pieces 1 are driven to move close to each other to clamp the woven bag. Then the lifting part 2 continues to move upward, and the clamping piece 1 clamps the woven bag and is lifted together with the lifting part 2, realizing the function of transporting the woven bag.

[0027] It should be noted that in the initial stage of lifting the lifting part 2, the clamping piece 1 may be lifted together with the lifting part 2, and the worker needs to hold the clamping piece 1 during use to prevent the clamping piece 1 from separating from the woven bag. After the clamping piece 1 clamps the woven bag, the worker releases his hand.

[0028] In this embodiment, in order to better fix the woven bag, the lower end of the clamping piece 1 is provided as an arc-shaped clamping section 11, and the arc-shaped clamping sections 11 of the two clamping pieces 1 are oppositely arranged. In this way, the fixing effect of the woven bag containing the dust rod is improved by the two arc-shaped clamping sections 11, facilitating transportation, and the structure is simple and practical.

[0029] In this embodiment, a connecting shaft 4 is arranged between the two clamping pieces 1, the two clamping pieces 1 are rotatably connected through the connecting shaft 4, a torsional spring 5 is sleeved on the connecting shaft 4, and the two ends of the torsional spring 5 are connected with the two clamping pieces 1 respectively. Under the action of the torsional spring 5, an opening force is applied to the two clamping pieces 1, which facilitates the opening of the two clamping pieces 1 during unloading, and the structure is simple and practical.

[0030] In this embodiment, an end head pressing block 6 is fixed to the clamping piece 1, an installation hole is formed in the end head pressing block 6, and the end of the torsional spring 5 is inserted into the installation hole. In this way, the connection between the torsional spring 5 and the clamping piece 1 is more stable, and the service life of the equipment is prolonged.

[0031] In other embodiments of the present application, the connection between the end of the torsional spring 5 and the clamping piece 1 can also be that the end of the torsional spring 5 directly abuts against the inner side wall of the clamping piece 1, which can also apply an opening force to the clamping piece 1. Compared with using the end head pressing block 6, the installation is more difficult, and the torsional spring 5 is prone to failure.

[0032] In this embodiment, the clamping piece 1 is symmetrically arranged about the lifting part 2. During lifting, the stress point is at the middle position of the clamp, and the lifting and transportation process is more stable, the structure is simple, and the practicality is strong.

[0033] Further, a avoiding slot 7 is formed in the middle of the clamping piece 1, a lifting rope 8 is connected to the lifting part 2, and the lifting rope 8 passes through the avoiding slot 7. According to the position of the lifting part 2, the position of the lifting rope 8 is designed, so that the structure of the clamp is more reasonable, the lifting and transportation of the dust rod are facilitated, the structure is simple, and the practicality is strong.

[0034] It can be understood that, in the present application, due to the limitation of the site, the electric control device cannot be used to transport the dust rod, the transportation device can be a wall or an upper rotatable frame installed on the ground, a tower spring balancer is arranged on the frame as a power source, and the lifting rope 8 is connected with the tower spring balancer. When the woven bag containing the dust rod needs to be transported, the frame is rotated to make the clamp located above the woven bag, the worker pulls down the clamp to clamp the woven bag, and the woven bag is automatically clamped after the pre-stress is released.

[0035] In the embodiment, the clamping piece 1 can include a plurality of clamping arms 12 and a plurality of connecting rods 13, the plurality of clamping arms 12 are arranged along the length direction of the clamping piece 1, and the clamping arms 12 are fixedly connected through the connecting rods 13. In this way, the clamping piece 1 forms a bracket structure, which reduces the weight of the lifting clamp, is beneficial to improve the bearing capacity of the lifting clamp, and reduces the equipment cost of the lifting clamp.

[0036] The principle of the present application is:

[0037] The clamp is moved above the woven bag containing the dust rod, the worker holds the clamping piece 1 to make the clamping piece 1 clamp the woven bag at the beginning of lifting, and then the lifting part 2 moves up, at this time, the lifting part 2 moves up relative to the clamping piece 1, the included angle between the two connecting plates 3 decreases, and the two clamping pieces 1 are driven to move close to each other to clamp the woven bag, the worker releases the clamping piece 1 when the clamping piece 1 clamps the woven bag, and the clamping piece 1 automatically clamps the woven bag to transport the woven bag.

[0038] When transported to above the transfer trolley, the clamp moves down to place the woven bag on the transfer trolley, and continues to move down, the included angle between the two connecting plates 3 increases, and at the same time, cooperates with the opening force of the torsional spring 5 on the two clamping pieces 1 to drive the two clamping pieces 1 to move away from each other to release the woven bag to complete unloading.

[0039] The lifting clamp provided by the present application is described in detail above. The description of the specific embodiment is only used to help understand the method and the core idea of the present application. It should be pointed out that, for ordinary skilled persons in the technical field, without departing from the principle of the present application, the present application can be improved and modified in many ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
