Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated beam plate hoisting, and in particular relates to a hoisting device for stainless steel corrugated beam plates of different lengths. Background Art

[0002] In the production and processing of stainless steel guardrails, the lifting and transportation links play a vital role. Due to the fixed structure of traditional lifting equipment, it is difficult to adapt to the diverse length requirements of corrugated beams, resulting in the need to frequently replace the lifting equipment during operations. This not only increases the construction cost burden, but also significantly reduces the overall construction efficiency. In addition, when using rope lifting, the sharp edges and corners of the guardrail directly act on the slings or lifting belts, which can easily cause serious wear and even breakage of the wire rope. Even with the protection of pads, the operation is still cumbersome, and irregular operations during the binding process, such as dragging the slings, deviation of the center of gravity, and loose binding, all pose potential safety hazards that cannot be ignored.

[0003] In response to the above-mentioned lifting difficulties, although some adjustable length hoists have appeared on the market, they still have shortcomings in terms of adjustment accuracy, stability, ease of operation and economic applicability. In addition, the original design was not specifically aimed at the lifting needs of guardrails, so there are many limitations in actual applications. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solution of the present invention is described in detail below in combination with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0027] like Figure 1 As shown in FIG. 5 , the utility model provides a hoisting device for stainless steel corrugated beam plates of different lengths, comprising a hoisting beam 1, on which two symmetrical moving seats 3 are slidably arranged, and a lifting claw 4 is respectively arranged at the lower end of each moving seat 3; a vertical fixing rod 5 is fixedly arranged on the lower end surface of the hoisting beam 1, and a driving bevel gear 6 and two symmetrical driven bevel gears 7 are rotatably arranged on the fixing rod 5, and the two driven bevel gears 7 are both meshed with the driving bevel gear 6; a screw rod 8 is respectively fixedly arranged on the two driven bevel gears 7, and the two screw rods 8 are respectively screwed to the inside of the two moving seats 3.

[0028] The lifting beam 1 is a square rod-shaped horizontally arranged along the left-right direction. Two symmetrical lifting ears 2 are fixedly arranged at both ends of the upper end surface of the lifting beam 1, and the lifting beam 1 is lifted by the lifting ears 2; a horizontal sliding board 9 is fixedly arranged at the lower edges of the front and rear end surfaces of the lifting beam 1, and a clamping strip 10 is fixedly arranged in the middle of the upper end surface of the sliding board 9, and the length direction of the clamping strip 10 is parallel to the length direction of the lifting beam 1.

[0029] The moving seat 3 is a square frame structure arranged horizontally, and a vertical outer connecting arm 11 is arranged at one end of the moving seat 3 away from the other moving seat 3, and a vertical T-shaped slot is arranged on the side of the outer connecting arm 11 facing the moving seat 3, and a T-shaped block is fixedly arranged on the side of the moving seat 3 facing the outer connecting arm 11, and the T-shaped block on the moving seat 3 is inserted into the T-shaped slot on the outer connecting arm 11. A vertical connecting plate is fixedly arranged at both ends of the upper end face of the outer connecting arm 11, and the connecting plate is located in a vertical plane in the left-right direction, and the two connecting plates are respectively located at the front and rear sides of the hoisting beam 1; two pulleys 13 are rotatably arranged on one side of the connecting plate close to the hoisting beam 1, and a circular groove is arranged in the middle of the outer cylindrical surface of the pulley 13, and the circular groove on the pulley 13 is slidably clamped on the clamping strip 10 of the sliding plate 9 on the same side, thereby realizing the stable rolling of the pulley 13 on the clamping strip 10.

[0030] Two vertical inner connecting arms 12 are fixedly arranged on the upper end surface of the moving seat 3 near the other end of the moving seat 3, and the upper ends of the two inner connecting arms 12 are respectively located on the front and rear sides of the hoisting beam 1; a pulley 13 is rotatably arranged on one side of the upper ends of the two inner connecting arms 12 near the hoisting beam 1, and a circular ring groove is arranged in the middle of the outer cylindrical surface of the pulley 13, and the circular ring groove on the pulley 13 is slidably clamped on the clamping strip 10 of the sliding board 9 on the same side, thereby realizing the stable rolling of the pulley 13 on the clamping strip 10. Limiting plates are fixedly arranged at both ends of the sliding board 9, and the limiting plates are used to prevent the pulley from escaping from the sliding board 9.

[0031] The active bevel gear 6 is rotatably arranged at the lower end of the fixed rod 5, and the rotating shaft of the active bevel gear 6 remains vertical. A vertical gripping rod is fixedly arranged at the lower end of the active bevel gear 6, and the gripping rod is parallel to the fixed rod 5. The active bevel gear 6 can be driven to rotate by controlling the gripping rod.

[0032] Two screw rods 8 are arranged horizontally along the left-right direction, and the two screw rods 8 are arranged symmetrically on both sides of the fixed rod 5, and the ends of the two screw rods 8 close to each other are rotatably connected to the fixed column. Two driven bevel gears 7 are fixedly arranged on the ends of the two screw rods 8 close to each other. The ends of the two screw rods 8 far away from each other are screwed to the inside of the two moving seats 3.

[0033] A fixing ring is fixedly provided at the lower end of the outer connecting arm 11 , a connecting chain 14 is provided on the fixing ring, the upper end of the connecting chain 14 is connected to the fixing ring, and the lower end of the connecting chain 14 is provided with the lifting claw 4 .

[0034] The lifting claw 4 includes a plurality of L-shaped rods 15 arranged front to back, the L-shaped rods 15 include a vertical section 16 and a horizontal section 17, the upper ends of the vertical sections 16 of the plurality of L-shaped rods 15 are connected to the lower ends of the corresponding connecting chains 14 through the same triangular frame 18, the horizontal section 17 is arranged horizontally along the left and right direction, and the end of the horizontal section 17 away from the lifting claw 4 on the other side is fixedly connected to the lower end of the vertical section 16. The horizontal section 17 of the L-shaped rod 15 is provided with a polyurethane anti-skid pad, and a self-locking mechanism is formed by the anti-skid pad to prevent the corrugated beam plate 20 from sliding during lifting. The lower end of the triangular frame 18 is inclined in the direction away from the lifting claw 4 on the other side. The vertical sections 16 of the plurality of L-shaped rods 15 are fixedly connected through a front and rear horizontal connecting rod 19.

[0035] Since one end of the movable seat 3 is plugged into the outer connecting arm 11, the lifting claws 4 on both sides only exert a downward pulling force on the outer connecting arm 11 during lifting, and do not exert the downward pulling force on the movable seat 3. In this way, the movable seat 3 will not be deformed by the downward pulling force when sliding, thereby ensuring that the screw 8 rotates normally inside the movable seat 3.

[0036] The working principle of the utility model is:

[0037] When the corrugated beam plate 20 needs to be hoisted, the driving bevel gear 6 is first rotated by controlling the gripping rod. Since the two driven bevel gears 7 are meshed with the driving bevel gear 6, the two driven bevel gears 7 drive the two screw rods 8 to rotate. Since the two screw rods 8 are respectively screwed with the two moving seats 3, when the screw rods 8 rotate, the two moving seats 3 are driven to move away from each other. The two moving seats 3 slide on the sliding plate 9 of the hoisting beam 1 through the pulleys 13 on the outer connecting arm 11 and the inner connecting arm 12. The annular groove on the pulley 13 is engaged with the clamping strip 10 of the sliding plate 9, which ensures the stable rolling of the pulley 13 on the clamping strip 10.

[0038] When the distance between the two lifting claws 4 is greater than the length of the corrugated beam plate 20 , the lifting beam 1 is controlled to move downward, so that the two lifting claws 4 move to below the outer sides of both ends of the corrugated beam plate 20 .

[0039] Then, the active bevel gear 6 is rotated by controlling the gripping rod, so that the two driven bevel gears 7 rotate in the opposite direction, thereby driving the two screw rods 8 to rotate in the opposite direction, so that the two moving seats 3 approach each other, so that the horizontal sections 17 of the L-shaped rods 15 of the two hanging claws 4 move to the lower sides of the two ends of the corrugated beam plate 20, until the vertical sections 16 of the L-shaped rods 15 of the two hanging claws 4 contact the two ends of the corrugated beam plate 20 and then the active bevel gear 6 stops rotating.

[0040] Then the hoisting beam 1 is controlled to be hoisted as a whole, at which time the horizontal sections 17 of the multiple L-shaped rods 15 of the two lifting claws 4 are respectively in contact with the multiple wave crests at both ends of the lower end surface of the corrugated beam plate 20, and the corrugated beam plate 20 is supported and fixed by the two lifting claws 4. In this way, the corrugated beam plate 20 can be hoisted smoothly.

[0041] Since the distance between the two lifting claws 4 can be adjusted in a wide range, corrugated beam plates 20 of different lengths can be lifted, which has higher applicability.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
