Description

Technical Field

[0001] This utility model relates to a protective device for vacuum suction cup lifting devices, belonging to the technical field of lifting equipment. Background Technology

[0002] Vacuum suction cups are essential equipment in the lifting and transporting of refrigerated truck body panels. They are used to protect the panels from scratches and damage. However, there is a risk of vacuum suction cups malfunctioning during transport, which could cause the panels to fall off and become unusable.

[0003] Therefore, when using vacuum suction cups to lift refrigerated truck body panels, a protective device needs to be installed. When the suction cups fail, the protective device can stably support the panels, providing active support and preventing the panels from falling and causing accidents to personnel or damage to the panels themselves. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the present invention aims to provide a vacuum suction cup lifting device. During the lifting of sheet metal, when the suction cup fails, the device can stably support the sheet metal, play an active support role, and prevent the sheet metal from falling and impacting personnel safety accidents and damage to the sheet metal itself.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A vacuum suction cup lifting device is characterized by comprising: a telescopic beam assembly, a cylinder assembly, and a support hook assembly; wherein the telescopic beam assembly includes a pair of fixed beams connected to the lifting device and a pair of movable beams; each of the fixed beams is provided with a cavity and is slidably fitted onto the corresponding movable beam; the cylinder assembly is used to adjust the length of the telescopic beam assembly, and the support hook assembly is installed at the end of the movable beam.

[0006] In the above solution, the movable beam is placed inside the fixed beam, which improves the space utilization rate. According to the width of the plate and the requirements of the working environment, the movable beam is driven to move along the fixed beam by one-button operation of the cylinder, and the length of the entire telescopic beam assembly can be freely adjusted to meet the hoisting needs of different widths.

[0007] Furthermore, the cylinder assembly includes: a cylinder body, a first connecting seat, and a second connecting seat; the cylinder bottom of the cylinder body is mounted between a pair of fixed beams via the first connecting seat, and the piston rod of the cylinder body is mounted between a pair of movable beams via the second connecting seat.

[0008] The first connecting seat includes: two connecting sleeves, a first support rod, and a first hinge seat. The two connecting sleeves are respectively fitted onto a pair of fixed beams. The first support rod is fixedly connected to the two connecting sleeves. The first hinge seat is installed on the first support rod and connected to the cylinder bottom of the cylinder body via a pin. The connecting sleeves are provided with threaded through holes. Fastening bolts are screwed into the corresponding threaded through holes and pressed tightly against the corresponding fixed beams, thereby fixing the first connecting seat to the fixed beams.

[0009] The second connecting seat includes: a second support rod and a second hinge seat; the second support rod is fixedly connected between a pair of movable beams, and the second hinge seat is installed on the second support rod and connected to the piston rod of the cylinder body through a pin.

[0010] In the above scheme, the symmetrical arrangement of the double beams ensures even distribution of cylinder thrust, preventing jamming caused by unilateral force. The connecting seat is detachable, allowing replacement of cylinders or related parts without disassembling the entire device. The hinged seat design allows the cylinder piston rod to tilt during movement and also cushions impacts. Loosening the fastening bolts and moving the connecting sleeve along the fixed beam as needed adjusts the position of the first connecting seat on the fixed beam; tightening the fastening bolts locks the position of the connecting sleeve, securing the first connecting seat to the fixed beam.

[0011] Furthermore, the support hook assembly includes: a pair of L-shaped hooks, a pair of adjusting bolts, a pair of springs, and a pair of support vertical tubes; the adjusting bolts are threaded to the top of the corresponding L-shaped hooks to form support hooks; the pair of support vertical tubes are respectively fixed to the ends of a pair of movable beams, and the support vertical tubes are provided with cavities for the support hooks to move up and down, and are sleeved on the outside of the corresponding support hooks; the springs are sleeved on the adjusting bolts and compressed between the head of the adjusting bolts and the top of the support vertical tubes.

[0012] In the above scheme, the L-shaped hook contacts the side end of the plate to support the plate's wall thickness and bottom. The height of the support hook can be adjusted by turning the adjusting bolt to make a coarse adjustment to accommodate plates of different thicknesses. By designing a spring, it can adapt to the plate's thickness, keeping the support hook close to the plate, and also prevent the plate from shaking and coming off the hook.

[0013] This utility model features a simple structure, easy installation, convenient operation, and wide applicability. The entire device is operated by a cylinder, enabling one-button operation and adapting to various lifting requirements. The support hook is equipped with a spring-loaded telescopic mechanism to accommodate different plate thicknesses and maintain constant contact with the plate, preventing lifting failure.

The fixed beams are provided with cavities and are slidably fitted onto the corresponding movable beams to form a telescopic beam structure.

[0017] like Figure 1 , Figure 2 As shown, the cylinder assembly includes: a cylinder body 3, a first connecting seat, and a second connecting seat. The cylinder bottom of the cylinder body is mounted between a pair of fixed beams via the first connecting seat, and the piston rod of the cylinder body is mounted between a pair of movable beams via the second connecting seat for adjusting the length of the telescopic beam assembly.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the first connecting seat includes: two connecting sleeves 4, a first support rod 5, and a first hinge seat 6. The two connecting sleeves 4 are respectively fitted onto a pair of fixed beams 1. The first support rod 5 is fixedly connected to the two connecting sleeves 4. The first hinge seat 6 is mounted on the first support rod and connected to the cylinder bottom of the cylinder body via a pin. All components are fully welded together.

[0019] In one embodiment of this utility model, the connecting sleeve 4 is provided with a threaded through hole, and the fastening bolt 7 is screwed into the corresponding threaded through hole and presses against the corresponding fixing beam. Loosening the fastening bolt can adjust the position of the first connecting seat on the fixing beam; tightening the fastening bolt can lock the position of the connecting sleeve.

The adjusting bolts are threaded onto the tops of the corresponding L-shaped hooks, forming the support hooks. The pair of support vertical tubes are respectively fixed to the ends of a pair of movable beams. Each support vertical tube has a cavity for the vertical displacement of the support hook and is fitted over the corresponding support hook. The springs are fitted over the adjusting bolts and compressed between the head of the adjusting bolt and the top of the support vertical tube. By turning the adjusting bolts, the overall height of the support hooks can be adjusted.
