Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a construction material hoisting equipment. Background Art

[0002] The four-column crane is a common hoisting tool, mainly composed of four columns, a carriage, a motor and other components. When in use, it needs to support the roof from above and the ground from below, and can extend to the outdoor for hoisting operations, and is commonly used in indoor decoration, construction and other scenarios.

[0003] When the existing four-column crane is in use, a push rod is used to push the whole carriage to the outdoor for hoisting operations. After the material is hoisted up, the carriage and the material can be pulled into the room by applying a pulling force, so as to complete a single hoisting operation. During the operation, since the carriage can move, the shaking of the material during the hoisting process is likely to cause the carriage to deviate. Therefore, in order to ensure the stability of the carriage, a stable thrust needs to be maintained on the carriage by the push rod all the time during the hoisting process. In order to simplify this operation, a construction material hoisting equipment is provided. Summary of the Invention

The pushing assembly 3 is used to move the hoisting assembly 2;

[0032] The hoisting assembly 2 further includes guide wheels 202, a fixed pulley 204, and a hook 205. The guide wheels 202 are symmetrically installed on both sides of the outer wall of the moving arm 201. The moving arm 201 is slidably connected to the inner side of the guide rail 103 through the guide wheels 202;

[0033] The fixed pulley 204 is rotatably connected to the bottom of the front end of the moving arm 201. The steel wire rope wound around the winding shaft of the winch 203 passes through the upper end of the fixed pulley 204 and extends below the fixed pulley 204 to be connected to the hook 205;

[0034] The pushing assembly 3 includes a pushing unit, a self-locking unit, and a reset unit. The pushing unit is used to assist the operator in manually pushing the hoisting assembly 2 for horizontal movement. The self-locking unit is used to lock the position of the hoisting assembly 2 and the guide rail 103 when the pushing unit is not subjected to an external thrust. The reset unit is used to provide a reset power for the pushing unit;

[0035] The pushing unit includes a concave frame 301, a camshaft 303, and a push rod 304;

[0036] The concave frame 301 is fixed to the rear end of the base of the winch 203. The camshaft 303 is rotatably connected to the inside of the concave frame 301. The push rod 304 is fixed to the bottom of the camshaft 303. The push rod 304 is used to provide a grasping position for the operator to facilitate applying a thrust or a pulling force to the hoisting assembly 2;

[0037] The self-locking unit includes a limit guide seat 302 and a positioning block 305;

[0038] The limit guide seat 302 is fixed to the rear end of the moving arm 201. The positioning block 305 is vertically slidably connected to the inside of the limit guide seat 302;

[0039] A plurality of uniformly distributed positioning grooves 104 are formed in the horizontal direction at the top of the guide rail 103. When the bottom of the positioning block 305 is in contact with the convex part of the camshaft 303, the top of the positioning block 305 penetrates through the top of the positioning groove 104 to lock the position of the moving arm 201 and the guide rail 103;

[0040] When the bottom of the positioning block 305 is in contact with the arc part of the camshaft 303, the top of the positioning block 305 is located below the positioning groove 104, which is used to release the position lock between the moving arm 201 and the guide rail 103;

[0041] The reset unit includes a limit baffle 306, a W-shaped elastic piece 307, and an elastic piece stopper 308;

[0042] The limit baffle 306 is fixed to the bottom end of the concave-shaped frame 301. The W-shaped elastic piece 307 is welded and fixed to the end face of the push rod 304 close to the limit baffle 306. A through groove penetrating both sides of the limit baffle 306 is provided at the contact position between the limit baffle 306 and the W-shaped elastic piece 307;

[0043] The elastic piece stopper 308 is fixed to one end of the limit baffle 306 away from the push rod 304 and is aligned with the through groove. The W-shaped elastic piece 307 penetrates the through groove and is in contact with the end face of the elastic piece stopper 308. The W-shaped elastic piece 307 is used to support the push rod 304 so that the push rod 304 is in an inclined state in the initial state;

[0044] The limit baffle 306 is used to limit the downward rotation of the push rod 304, and the deformed W-shaped elastic piece 307 is used to provide the reset power for the push rod 304.

[0045] In this embodiment: In the daily state, the push rod 304 is in an inclined downward state. At this time, the cam part of the camshaft 303 is in contact with the bottom of the positioning block 305, and the positioning block 305 is in a lifted state. At this time, the positioning block 305 penetrates a positioning groove 104, that is, the entire lifting assembly 2 cannot move horizontally at this time, so as to ensure the stable operation of the lifting assembly 2;

[0046] When it is necessary to move the lifting assembly 2 horizontally, only need to hold the push rod 304 and apply a thrust or a pull force to it. The push rod 304 can first drive the camshaft 303 to rotate, so that the cam of the camshaft 303 deviates from the positioning block 305, and then relieve the extrusion of the positioning block 305. The positioning block 305 contracts downward under its own gravity, releases the engagement with the positioning groove 104, and then continue to apply a pull force or a thrust force to drive the entire lifting assembly 2 to move;

[0047] After the lifting assembly 2 moves to a suitable position, release the push rod 304. At this time, the push rod 304 can be reset to the initial state under the action of the W-shaped elastic piece 307 or its own gravity. The convex part of the camshaft 303 squeezes the positioning block 305 again, and the positioning block 305 moves up and is stuck into another positioning groove 104, so as to realize the re-fixation of the lifting assembly 2;

[0048] When the push rod 304 is released and the positioning block 305 is not aligned with the positioning groove 104, the push rod 304 maintains a reset trend at this time. When the hoisting assembly 2 is offset during operation later, the positioning block 305 is driven to move synchronously and align with a positioning groove 104. At this time, the push rod 304 resets, and the positioning block 305 moves upward and engages with this positioning groove 104, thereby fixing the hoisting assembly 2. In this way, excessive offset of the hoisting assembly 2 can be avoided, and it can maintain a stable state during subsequent operation.

[0049] Please refer specifically to Figures 1 to 3 , the width of the push rod 304 is greater than the width of the through hole, and the rotation angles between the push rod 304 and the limit baffle 306 and between the push rod 304 and the rear end of the concave frame 301 are greater than the distribution angle of the convex portions of the camshaft 303.

[0050] In this embodiment: It should be noted that when pushing forward, the limit baffle 306 is used to limit the rotation of the push rod 304, and when pulling backward, the cross arm at the rear end of the concave frame 301 is used to limit the rotation of the push rod 304;

[0051] Through the above structure, the convex portions of the camshaft 303 are completely rotated away from the positioning block 305, and then the extrusion on the positioning block 305 is fully released.

[0052] The above-mentioned is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
