Description

Technical Field

[0001] This utility model relates to the field of lifting clamp technology, and more specifically, to a semi-trailer beam lifting clamp. Background Technology

[0002] The frame is a core structural component in automotive engineering, professionally known as the chassis. It consists of two longitudinal beams and multiple transverse beams welded or riveted together to form a trapezoidal frame. This structure serves as the vehicle's base, bearing the weight of core components such as the engine and transmission, and transmitting impact loads generated during driving.

[0003] Currently, when adjusting the spacing of the clamps for hoisting beams, workers usually need to remove the bolts, move the clamps to the required distance, and then fix them with bolts. This process is quite cumbersome. In addition, most clamps are pre-drilled during production, and the limited number of holes reduces the flexibility of adaptation. Therefore, we need to solve this problem in a timely manner. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a semi-trailer beam lifting clamp, which is set up in sections by the movable component and the positioning component, and utilizes the hexagonal groove formed between the first trapezoidal block and the second trapezoidal block to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a semi-trailer beam lifting clamp, comprising, The main component includes a load-bearing frame, a movable component slidably connected to the inner side of the load-bearing frame, and a positioning component fixedly installed at the bottom of the inner side of the load-bearing frame. The load-bearing frame is rectangular in shape, and the inner height of the load-bearing frame is greater than the sum of the height of the movable component and the positioning component. A threaded cylinder is fixedly installed on the top of the load-bearing frame, and a stud is threadedly connected to the inner side of the threaded cylinder. An adjusting plate is fixedly installed on the top of the stud.

[0006] In a preferred embodiment, the movable component includes an upper pressure plate that is slidably connected to the inner side of the load-bearing frame. The bottom of the upper pressure plate is provided with a first trapezoidal block, the bottom of the first trapezoidal block is provided with a trigger block, and the bottom of the upper pressure plate is provided with a pressure block. The stud is rotatably connected to the top of the upper pressure plate.

[0007] In a preferred embodiment, the positioning component includes a positioning plate, a second trapezoidal block is provided on the top of the positioning plate, a movable clamping block is slidably connected to the inner side of the second trapezoidal block, a spring is provided on one side of the movable clamping block, and one end of the spring abuts against the positioning plate.

[0008] In a preferred embodiment, the number of the first trapezoidal blocks and the second trapezoidal blocks is set to a plurality, and the plurality of the first trapezoidal blocks and the second trapezoidal blocks are arranged in a linear array about the inner side of the load-bearing frame, and a hexagonal groove is formed between the plurality of the first trapezoidal blocks and the second trapezoidal blocks.

[0009] In a preferred embodiment, the number of movable clamping blocks is set to multiple, and the multiple movable clamping blocks are arranged in a mirror symmetrical manner about the center line of the trigger block, and the side of the multiple trigger blocks adjacent to the movable clamping blocks is provided with an inclined surface.

[0010] In a preferred embodiment, the fixing component includes a bolt that is inserted into a hexagonal groove in the first trapezoidal block and the trigger block, a U-shaped buckle is inserted into the outside of the bolt, and a clamping arm is sleeved at the bottom of the U-shaped buckle.

[0011] The technical effects and advantages of this utility model are as follows: 1. This utility model is designed with a movable component and a positioning component. The movable component and the positioning component are set in sections, so when the upper pressure plate rises, the bolts do not need to be removed and re-inserted. The hexagonal groove formed between the first trapezoidal block and the second trapezoidal block eliminates the need for pre-drilling. The multiple hexagonal grooves also improve the applicability and make adjustment more convenient. 2. This utility model incorporates a trigger block. When the upper pressure plate descends, the trigger block contacts the movable clamping block, thereby pushing the movable clamping block to slide outward and hold the bolt in place on both sides. At the same time, the pressure block presses on top of the bolt, achieving a three-point fixation. After hoisting, when the upper pressure plate rises, the trigger block loses contact with the movable clamping block. At this time, the positioning component rebounds and pushes the movable clamping block to reset, thus improving stability and convenience. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Refer to the appendix of the instruction manual. Figure 1 A semi-trailer beam lifting clamp, comprising, The main component 100 includes a load-bearing frame 101, a movable component 102 slidably connected to the inner side of the load-bearing frame 101, and a positioning component 103 fixedly installed at the bottom of the inner side of the load-bearing frame 101. The load-bearing frame 101 is rectangular in shape. The inner height of the load-bearing frame 101 is greater than the sum of the height of the movable component 102 and the positioning component 103. This arrangement provides space for the movable component 102 to slide, and the load-bearing frame 101 supports and limits the movable component 102 and the positioning component 103. A threaded cylinder 105 is fixedly installed on the top of the load-bearing frame 101. A stud 106 is threadedly connected to the inner side of the threaded cylinder 105. An adjusting plate 107 is fixedly installed on the top of the stud 106. By rotating the adjusting plate 107, the stud 106 is rotated, thereby driving the movable component 102 to rise and fall. The threaded cylinder 105 is used to fix the stud 106. The fixing component 200 includes a bolt 201, which is inserted into the hexagonal groove of the first trapezoidal block 102b and the trigger block 102c. A U-shaped buckle 202 is inserted into the outside of the bolt 201, and a clamping arm 203 is sleeved on the bottom of the U-shaped buckle 202.

[0018] Regarding the above technical solution, it should be noted that when this device is actually used, by rotating the adjusting plate 107, the stud 106 rotates, thereby driving the movable component 102 to rise and fall. When the movable component 102 is raised, the sliding bolt 201 can be used to adjust the spacing so that the clamping arm 203 and the semi-trailer beam can be matched, thus facilitating hoisting. When the movable component 102 is lowered, the bolt 201 can be limited to prevent the bolt 201 from sliding and causing the spacing between the two clamping arms 203 to change.

[0019] Example 2: Refer to the appendix of the instruction manual. Figure 2-3The active component 102 includes an upper pressure plate 102a, which is slidably connected to the inner side of the load-bearing frame 101. The bottom of the upper pressure plate 102a is provided with a first trapezoidal block 102b, the bottom of the first trapezoidal block 102b is provided with a trigger block 102c, the bottom of the upper pressure plate 102a is provided with a pressure block 102d, and the stud 106 is rotatably connected to the top of the upper pressure plate 102a. The positioning component 103 includes a positioning plate 103a, a second trapezoidal block 103b on the top of the positioning plate 103a, a movable clamping block 103c slidably connected to the inner side of the second trapezoidal block 103b, a spring 103d on one side of the movable clamping block 103c, and one end of the spring 103d abutting against the positioning plate 103a. The number of first trapezoidal blocks 102b and second trapezoidal blocks 103b is set to multiple. The multiple first trapezoidal blocks 102b and second trapezoidal blocks 103b are arranged in a linear array about the inner side of the load-bearing frame 101. A hexagonal groove is formed between the multiple first trapezoidal blocks 102b and the second trapezoidal blocks 103b. The number of movable clamping blocks 103c is set to multiple. The multiple movable clamping blocks 103c are arranged in a mirror symmetrical shape about the center line of the trigger block 102c. The side of the multiple trigger blocks 102c adjacent to the movable clamping blocks 103c is provided with a slope. Bolts 201 are inserted into the hexagonal grooves of the first trapezoidal blocks 102b and the second trapezoidal blocks 103b. A U-shaped buckle 202 is threaded on the outside of the bolt 201. A clamping arm 203 is sleeved on the bottom of the U-shaped buckle 202.

[0020] Regarding the above technical solution, it should be noted that when the spacing of the clamping arms 203 needs to be adjusted during actual use of this device, the adjusting disc 107 is rotated to raise the upper pressure plate 102a, and then the bolt 201 is moved to the required position. After the clamping arms 203 support the beam, the adjusting disc 107 is rotated to lower the upper pressure plate 102a. Then, the trigger block 102c contacts the movable clamping block 103c. By using a sloped contact surface, the movable clamping block 103c is pushed to slide outward, thereby fixing the two sides of the bolt 201. At the same time, the pressure block 102d presses on the bolt 201 to achieve three-point fixation, preventing the bolt 201 from rotating and affecting stability during hoisting. After hoisting is completed, when the upper pressure plate 102a rises, the trigger block 102c loses contact with the movable clamping block 103c. At this time, the positioning component 103 rebounds and pushes the movable clamping block 103c to reset.
