Description

Technical Field

[0001] This utility model relates to the field of hoisting clamp technology, specifically to a hoisting clamp device for red-mounted drill rods. Background Technology

[0002] The field of lifting clamp technology mainly involves specialized tools for lifting, handling, and loading / unloading heavy objects. During the hot-loading process of drill rods, the drill rods need to be lifted at high temperatures. Hot-loading drill rod lifting clamp devices can meet the lifting requirements when the drill rods enter and exit the heating furnace under high-temperature conditions, effectively handling the lifting operations of drill rods in the "hot-loading" state.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] During the red-loading process of the drill rod, the drill rod needs to be hoisted at high temperatures. Existing drill rod hoisting fixtures do not take into account the high-temperature state of the drill rod during the red-loading process, making the fixtures unable to withstand such high-temperature environments. This causes the fixtures to easily deform or fail due to high temperatures, making them unsuitable for use in the red-loading state and unable to meet the hoisting and transportation requirements for entering and exiting the heating furnace during the red-loading process. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting clamp device for red-mounted drill rods, in order to solve the problem mentioned in the background art that the clamp cannot withstand the high temperature environment when the drill rod is in the "red-mounted" high-temperature state, which easily leads to deformation or failure of the clamp due to high temperature, and is not suitable for use in the "red-mounted" state.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting clamp device for a chisel rod, comprising a second lifting body, a rotating shaft of the second lifting body welded to the bottom end of one side of the second lifting body, a first lifting body rotatably connected to both ends of the rotating shaft of the second lifting body, and a limit block installed on one side of the top end of the first lifting body.

[0007] A rotary locking assembly is screwed onto the top of the second main body of the lifting device.

[0008] The rotating locking assembly includes a base screwed to the top of the second body of the lifting device. A pull rod is slidably connected to one side of the base. One end of the pull rod surface has a threaded groove. A limit ring is installed on the end of the pull rod surface near the threaded groove. A return spring is sleeved in the middle of the pull rod surface.

[0009] The beneficial effects of this utility model are as follows: the hoisting clamp still has sufficient strength and flexibility of use in the high temperature "red-coated" state, effectively avoiding deformation or failure caused by high temperature, and is suitable for use in the "red-coated" state. It helps to meet the hoisting and transportation needs of entering and exiting the heating furnace in the "red-coated" state, and can fully guarantee the safety technical requirements during use. It is also stable, convenient, quick, reusable, economical, energy-saving and environmentally friendly.

[0010] To ensure that the lifting equipment can be lifted in a balanced and stable manner, and to maintain a stable center of gravity during lifting, so that the drill rod is not prone to tilting or swaying during lifting:

[0011] The configuration is further defined as follows: both the second body of the lifting device and the first body of the lifting device have main lifting lugs welded to the middle of one side.

[0012] By adopting the above technical solution, main lifting lugs are symmetrically set at both ends, thereby assisting the lifting device in maintaining a stable center of gravity during lifting, preventing the drill rod from tilting or swaying during lifting, and ensuring balance and safety during the lifting process.

[0013] To ensure that the end of the tie rod with a threaded hole can be fully screwed into the threaded hole by the rotation of the tie rod itself:

[0014] The setting is further configured such that a threaded hole is provided on one side of the limiting block, and the internal size of the threaded hole is consistent with the external size of the pull rod.

[0015] By adopting the above technical solution, the end of the pull rod with a threaded hole on its surface can be rotated by rotating the handle, and then the end of the pull rod can be screwed into the threaded hole through a threaded connection to fix the limit block.

[0016] To ensure that the threaded end of the tie rod has a threaded groove, and the threaded connection is inside the threaded hole, it is less susceptible to loosening and falling off due to external environmental impacts and collisions:

[0017] The setting is further configured such that: the limiting ring forms a buffer structure with the base through a reset spring, and a handle is installed on one side of the pull rod, and the pull rod forms a pull-out structure with the base through the handle.

[0018] By adopting the above technical solution, the elastic force of the return spring itself can be combined with the limiting ring to continuously provide a pushing force toward the limiting hole to one end of the pull rod screwed into the threaded hole, thus avoiding the possibility of loosening of the threaded connection.

[0019] To ensure that the entire fixture is unaffected by the high temperature of the drill bit during hoisting, and to prevent deformation or failure of the fixture due to high temperature:

[0020] Further configuration: the second main body, the rotating shaft of the second main body of the lifting device, the first main body of the lifting device, the limit block and the rotating locking assembly are all made of nickel-based high-temperature alloy.

[0021] By adopting the above technical solutions, the fixtures cast from nickel-based high-temperature alloys can maintain lattice stability at high temperatures, improve creep resistance, and ensure that the overall lifting fixture still has sufficient strength in the high-temperature "red-coated" state, which helps to smoothly carry out the "red-coated" lifting operation of the drill rod.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0028] Please see Figures 1 to 3 The rod hoisting clamp device includes a second main body 1 of the hoisting device. A rotating shaft 2 is welded to the bottom end of one side of the second main body 1. The two ends of the rotating shaft 2 are rotatably connected to the first main body 3 of the hoisting device. A limit block 4 is installed on one side of the top of the first main body 3 of the hoisting device.

[0029] The top of the second main body 1 of the lifting device is equipped with a rotary locking assembly 5 by screws.

[0030] The rotating locking assembly 5 includes a base 501 that is screwed to the top of the second body 1 of the lifting device. A pull rod 502 is slidably connected to one side of the base 501. A threaded groove 503 is provided at one end of the surface of the pull rod 502. A limit ring 504 is installed at the end of the surface of the pull rod 502 near the threaded groove 503. A return spring 505 is sleeved in the middle of the surface of the pull rod 502.

[0031] In this embodiment, as Figure 1 As shown, the second main body 1 of the lifting device and the middle part of one side of the first main body 3 of the lifting device are both welded with main lifting lugs 6.

[0032] In this embodiment, as Figure 2 As shown, a threaded hole is provided on one side of the limiting block 4, and the internal size of the threaded hole is consistent with the external size of the pull rod 502.

[0033] In this embodiment, as Figure 3 As shown, the limiting ring 504 forms a buffer structure with the base 501 through the return spring 505, and a handle is installed on one side of the pull rod 502, and the pull rod 502 forms a pull-out structure with the base 501 through the handle.

[0034] In this embodiment, as Figure 1 As shown, the second main body, the rotating shaft 2, the first main body of the lifting device 3, the limiting block 4, and the rotating locking assembly 5 are all made of nickel-based high-temperature alloy.

[0035] The working process of this drill rod hoisting clamp device is as follows:

[0036] First, the operator processes each component in this technical solution according to the required dimensions. Then, the rotating shaft 2 is placed at the bottom of one side of the second main body 1 of the lifting device. Next, the bottom of the first main body 3 of the lifting device is rotated and set at both ends of the rotating shaft 2. Finally, the rotating locking assembly 5 can be placed on the top of the second main body 1 of the lifting device, thus completing the sub-assembly. After all components are inspected and tested and qualified, they are welded together as one unit. After welding, the flexibility of each rotating and moving part is tested again. If there are no problems, the welding stress relief heat treatment is performed. After the heat treatment process is completed, the lifting fixture is cooled and then used in a simulated "red-clad" state at room temperature to test its load-bearing safety and the flexibility of each position. If it passes the test, it is then put into "red-clad" state for use.
