Description

Technical Field

[0001] The utility model relates to the field of cranes, in particular to a construction lifting device with a lifting tool. Background Art

[0002] Gantry crane, also known as gantry crane, is a deformation of bridge crane. The metal structure of gantry crane is like a door-shaped frame. Two legs are installed under the main beam. It can walk directly on the track on the ground. Both ends of the main beam can have outward cantilever beams. It has the characteristics of high site utilization, large operating range, wide adaptability and strong versatility.

[0003] After searching the announcement number CN221253644U, a trackless gantry crane is found, including a fixed plate, mounting frames are installed on both sides of the bottom end of the fixed plate, support rods are installed on the bottom end of the mounting frames, adjusting mechanisms are installed on the bottom ends of the support rods, electric wheels are installed on the bottom ends of the adjusting mechanisms, a first motor is installed on the left side of the top end of the fixed plate, a threaded rod is installed on the right side of the output shaft of the first motor, a movable mechanism is installed on the right side of the top end of the fixed plate, the right side of the threaded rod is installed inside the movable mechanism, a threaded sleeve is threadedly installed on the middle part of the threaded rod, a support frame is transversely installed on the bottom end of the fixed plate, a movable plate is movably installed in the middle of the inner cavity of the support frame, a sling is installed on the bottom end of the movable plate, a sliding hole is transversely opened in the middle of the fixed plate, and the top of the movable plate A connecting rod is installed in the middle of the end, and the top of the connecting rod passes through the sliding hole and is connected to the threaded sleeve. According to the above application documents, the gantry crane mainly lifts objects through the sling when in use, and the figure shows that the sling is mainly composed of a sling and a lifting hook. According to the prior art, when the sling is wound, the lifting hook can be lifted upward, and when the sling is lowered, the lifting hook can be dropped. During use, the hoisted objects need to be fixed with ropes in advance, and then the ropes of the hoisted objects can be put into the hoisting hook for hoisting. However, the sling and the hoisting hook are fixedly connected, which is not convenient for disassembly and assembly to replace slings and hoisting hooks of different sizes. At the same time, no protective structure is set on one side of the hoisting hook. When the hoisting hook hooks the rope of the hoisted object and lifts it upward, the rope can easily fall off from one side of the hoisting hook, and the overall protection is not ideal.

[0004] Therefore, it is necessary to invent a kind of building lifting equipment with lifting tool. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

Then the limit plate is released to make the compression spring rebound. At this time, the protrusion can limit one end of the limit plate to prevent the rope of the hoisting object from being separated from the hoisting hook.

[0014] Preferably, the limiting plate is arranged in an inclined shape, and one end of the limiting plate away from the rotating shaft is in active contact with the protrusion.

[0015] Based on the above characteristics: it is convenient for the limiting plate to block the lifting hook.

When the card grooves on both sides of the T-shaped slider are aligned with the through groove, the pull plate can be loosened to make the buffer spring rebound and the card block be stuck into the internal limit of the card groove. When disassembly is required, it is only necessary to pull the card block out of the card groove through the pull plate again. It is simple and convenient.

[0022] 2. To prevent the hoisted objects from falling off from one side of the lifting hook, before the rope of the hoisted object is hoisted by the lifting hook, you can press the limit plate away from the protrusion. At this time, a gap will be left between the limit plate and the protrusion to facilitate the rope of the hoisted object to fall into the inside of the hoisting hook. Then release the limit plate to allow the compression spring to rebound. At this time, the protrusion can limit one end of the limit plate to prevent the rope of the hoisted object from separating from the hoisting hook. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0029] See attached Figure 1-4 The utility model provides a construction lifting equipment with a lifting tool, including a gantry crane 1, a sling 2 is connected to the lower end of the gantry crane 1, a fixing seat 3 is fixedly installed at the lower end of the sling 2, a lifting hook 4 is arranged at the lower end of the fixing seat 3, a protrusion 5 is installed on one side of the lifting hook 4, and a connecting seat 6 is fixedly installed on the top of the lifting hook 4.

[0030] The lifting hook 4 can be used to hook the rope for lifting objects. The lifting hook 4 is connected to the bottom of the fixing seat 3 through the connecting seat 6, which is convenient for the lifting hook 4 to be movable and assembled. The provided protrusion 5 can limit the rope for lifting objects to prevent the objects from falling off after being lifted. When the sling 2 is wound, the sling 2 can drive the lifting hook 4 to rise upward through the fixing seat 3. At this time, the hooked object will also move upward. When the sling 2 is lowered, the sling 2 can drive the lifting hook 4 to fall through the fixing seat 3. At this time, the hooked object will also move downward (the sling 2 can be wound and released through workpieces such as a rotating motor, a winding roller, and a directional pulley. This is the prior art and the specific details will not be repeated).

[0031] Preferably, a T-shaped slot 31 is provided at the lower end of the fixing seat 3 , through slots 32 are symmetrically provided on the inner walls at both ends of the T-shaped slot 31 , a clamping block 33 is movably passed through the through slot 32 , and movable slots 34 are symmetrically provided on the surfaces at both ends of the fixing seat 3 .

[0032] The lifting hook 4 is connected to the T-shaped slide groove 31 below the fixing seat 3 through the connecting seat 6, and the clamping block 33 can be movably penetrated through the through groove 32, so that after the connecting seat 6 is connected to the fixing seat 3, the clamping block 33 can be extended to clamp and limit the connection between the two to prevent the two from separating by themselves.

[0033] Preferably, a buffer spring 331 is installed at one end of the clamping block 33 , and a pull plate 332 is installed at the side of one end of the clamping block 33 close to the buffer spring 331 , and the pull plate 332 movably passes through the movable groove 34 .

[0034] When the connecting seat 6 is connected to the fixing seat 3, the block 33 can be pulled back to the inside of the through slot 32 by the pull plate 332. At this time, the buffer spring 331 will be squeezed and deformed. When the pull plate 332 is released, the buffer spring 331 can rebound the block 33 to extend out of the through slot 32. Since the pull plate 332 is limited to the inside of the movable slot 34, it can not only prevent the block 33 from detaching from the through slot 32 when it rebounds, but also facilitate personnel to pull the pull plate 332 and the block 33 to move.

[0035] Preferably, a rotating shaft 41 and a limiting plate 42 are installed on one side of the upper end of the lifting hook 4, one end of the limiting plate 42 is movably hinged to the lifting hook 4 through the rotating shaft 41, and a compression spring 43 is connected between the limiting plate 42 and the lifting hook 4.

[0036] The limiting plate 42 can be rotated by the rotating shaft 41. Before the rope of the hoisting object is hoisted by the hoisting hook 4, the limiting plate 42 can be pressed away from the protrusion 5. At this time, a gap will be left between the limiting plate 42 and the protrusion 5, which is convenient for the rope of the hoisting object to fall into the inside of the hoisting hook 4. Then the limiting plate 42 is loosened to make the compression spring 43 rebound it. At this time, the protrusion 5 can limit one end of the limiting plate 42 to prevent the rope of the hoisting object from being separated from the hoisting hook 4.

[0037] Preferably, the limiting plate 42 is arranged in an inclined shape, and one end of the limiting plate 42 away from the rotating shaft 41 is in active contact with the protrusion 5 .

[0038] The limiting plate 42 is convenient for blocking the lifting hook 4.

[0039] Preferably, a T-shaped slider 61 is fixedly mounted on the upper end of the connecting seat 6 , and slots 62 are symmetrically provided on both sides of the T-shaped slider 61 .

[0040] The connecting seat 6 is inserted into the T-shaped slide groove 31 at the lower end of the fixed seat 3 through the T-shaped slider 61. When the slots 62 on both sides of the T-shaped slider 61 are aligned with the through slot 32, the movement of the connecting seat 6 can be stopped, so that the block 33 can extend out of the through slot 32 and be inserted into the slot 62 for fixed positioning.

[0041] Preferably, the T-shaped sliding block 61 is slidably connected to the T-shaped sliding groove 31 .

[0042] The connecting seat 6 and the fixing seat 3 can be conveniently inserted or pulled out for connection.

[0043] The use process of the utility model is as follows: when the lifting hook 4 needs to be installed, the connecting seat 6 is inserted into the T-shaped slide groove 31 at the lower end of the fixing seat 3 through the T-shaped slide block 61. At this time, the card block 33 can be pulled back to the inner side of the through groove 32 by the pull plate 332, and the retracted card block 33 will squeeze the buffer spring 331 to deform. When the card grooves 62 on both sides of the T-shaped slide block 61 are aligned with the through groove 32, the pull plate 332 can be released to make the buffer spring 331 rebound the card block 33. At this time, the card block 33 can extend out of the through groove 32 and be stuck in the inner limit of the card groove 62. When it needs to be disassembled, it only needs to be removed again The block 33 is pulled out of the slot 62 by the pull plate 332, and then the connecting seat 6 is moved to separate the T-shaped slider 61 from the T-shaped slot 31. Before the rope of the hoisting object is hoisted by the hoisting hook 4, the limit plate 42 can be pressed away from the protrusion 5. At this time, a gap will be left between the limit plate 42 and the protrusion 5, so that the rope of the hoisting object can fall into the inside of the hoisting hook 4. Then the limit plate 42 is loosened to make the compression spring 43 rebound. At this time, the protrusion 5 can limit one end of the limit plate 42. Finally, the winding sling 2 can drive the hoisting hook 4 to hoist the object upward through the fixed seat 3.

[0044] The above is only a preferred embodiment of the utility model. Any person skilled in the art may modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
