Description

Technical Field

[0001] This utility model relates to the field of lifting machinery protection technology, and in particular to a safety protection structure for lifting machinery. Background Technology

[0002] Lifting machinery refers to electromechanical equipment used for vertical lifting or vertical lifting and horizontal movement of heavy objects. Lifting machinery lifts or moves heavy objects by means of lifting hooks or other lifting devices. The working process of lifting machinery generally includes steps such as lifting, running, lowering and returning to the original position.

[0003] Currently, during cargo lifting, the lifting rope is usually first put on the cargo, then the top of the lifting rope is put on the hook of the lifting machinery, and then the crane hook is used to lift and transfer the cargo.

[0004] However, in actual lifting operations, the traditional method of transporting goods by ropes is not stable enough. After being lifted, the goods are very prone to swaying, which increases the risk of falling during transportation. Furthermore, since the goods transported by cranes are usually very heavy, the cargo box will be subjected to a large impact force due to inertia at the moment of hard landing, causing the goods to vibrate and increasing the risk of damage, which is not conducive to the safe transportation of goods. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the prior art that the lack of protective structure when goods are hoisted not only increases the risk of goods falling but also the risk of goods being damaged, which is not conducive to the safe transportation of goods. Therefore, a safety protection structure for hoisting machinery is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A safety protection structure for lifting machinery includes a protective box with an opening on one side and a base, and further includes: two protective doors, both rotatably connected to the opening of the protective box, wherein each protective door is provided with a push-pull part for driving the protective door to open and close. When the protective door is closed, the protective door and the protective box form a closed space for wrapping goods; a buffer shell, fixedly connected to the bottom of the protective box, wherein the buffer shell is slidably mounted on the base, and the base is provided with a buffer part for cushioning the movement of the buffer shell within the base.

[0008] To provide cushioning protection for the goods, preferably, the buffer includes a straight rod fixedly connected to the base, with movable blocks slidably mounted on both sides of the outer wall of the straight rod, and springs sleeved on the movable blocks. The two ends of the springs are respectively fixedly connected to the two movable blocks. A movable rod is rotatably connected to the movable block, and the end of the movable rod away from the movable block is rotatably connected to the bottom of the buffer shell. A damping element is provided on the straight rod.

[0009] In order to guide the buffer shell, preferably, sliders are fixedly connected to both sides of the buffer shell, and grooves are opened on both sides of the inner wall of the base, and the sliders are slidably connected in the grooves in the longitudinal direction.

[0010] To further improve the buffering effect, the damping component includes a buffer airbag sleeved on a straight rod. The two ends of the buffer airbag are respectively fixedly connected to the inner wall of the base and the surface of the moving block. The buffer airbag is connected to an air inlet pipe and an air outlet pipe, both of which extend to the outside of the base. A one-way valve is installed inside the air inlet pipe and the air outlet pipe.

[0011] To improve the stability of the moving block, the straight rod is further designed to be square, and the moving block is laterally slidably connected to the straight rod.

[0012] To further filter the air entering the airbag, a filter element is fixedly installed on the air intake pipe, and the filter element is arranged at the air intake port of the air intake pipe.

[0013] To facilitate opening and closing of the protective door, preferably, the push-pull part includes a guide sleeve fixedly connected to the protective door, a fixed rod slidably connected to the guide sleeve, and a locking element provided on the fixed rod.

[0014] To further secure the protective door, the locking component includes a limiting frame fixedly connected to the protective box, and a fixing rod inserted into the limiting frame. A buckle is fixedly connected to the surface of the protective door, and a locking plate is fixedly connected to the surface of the fixing rod, with the locking plate engaging with the buckle.

[0015] To facilitate the connection of the hook of the lifting machinery, preferably, a bracket is fixedly connected to the top of the protective box, and a lifting ring is fixedly connected to the bracket.

[0016] To better mitigate the impact, preferably, an elastic pad is fixedly connected to the bottom of the base, and the surface of the elastic pad is provided with anti-slip texture.

[0017] Compared with the prior art, this utility model provides a safety protection structure for lifting machinery, which has the following beneficial effects:

[0018] 1. The safety protection structure for this lifting machinery, through the combined use of a protective box, protective door, fixed rod, and limit frame, can form a closed space to wrap and protect the goods, thereby greatly reducing the risk of goods falling during transportation.

[0019] 2. The safety protection structure for this lifting machinery, through the combined use of the base, buffer shell, moving block and spring, can greatly absorb and weaken the impact force received by the protective box when it lands, so as to achieve the function of buffering and protecting the goods inside the protective box, thereby greatly reducing the risk of damage to the goods and improving the safety of cargo transportation.

[0020] 3. The safety protection structure for this lifting machinery, through the setting of buffer airbags, air intake pipes and exhaust pipes, can further weaken the impact force received by the protective box when it lands, thereby improving the buffer protection effect on the cargo, and can also provide motion damping force for the moving block, thereby quickly calming unnecessary movement in the structure and suppressing the occurrence of resonance effect, which helps to improve the overall stability of the protective structure.

[0029] Example:

[0030] Reference Figures 1-4 This utility model embodiment provides a safety protection structure for lifting machinery, including a protective box 1 with an opening on one side and a base 3, and further including: two protective doors 2, both rotatably connected to the opening of the protective box 1, wherein the protective doors 2 are provided with a push-pull part, which is used to drive the protective doors 2 to open and close. When the protective doors 2 are closed, the protective doors 2 and the protective box 1 form a closed space for wrapping goods. A bracket 8 is fixedly connected to the top of the protective box 1, and a lifting ring 81 is fixedly connected to the bracket 8, which can easily connect to the hook of the lifting machinery, thereby facilitating the lifting machinery to lift the protective box 1 containing goods; a buffer shell 4 is fixedly connected to the bottom of the protective box 1, wherein the buffer shell 4 is slidably installed on the base 3, and the base 3 is provided with a buffer part, which is used to make the buffer shell 4 perform buffering movement within the base 3. An elastic pad 9 is fixedly connected to the bottom of the base 3, and the surface of the elastic pad 9 is provided with anti-slip texture, which can better weaken the impact force, improve the protection effect, and also improve the anti-slip performance of the bottom of the base 3.

[0031] Specifically, in use, the protective box 1, the protective door 2, and the push-pull part work together to form a closed space to wrap and protect the goods, thereby greatly reducing the risk of the goods falling during transportation. Furthermore, the buffer part can absorb and weaken the impact force when the protective box 1 lands, thereby achieving the function of buffering and protecting the goods inside the protective box 1, which greatly reduces the risk of damage to the goods and helps to improve the safety of goods transportation.

[0032] The buffer section includes a straight rod 5 fixedly connected to the base 3. Movable blocks 51 are slidably installed on both sides of the outer wall of the straight rod 5. Springs 52 are sleeved on the movable blocks 51. The two ends of the springs 52 are fixedly connected to the two movable blocks 51 respectively. A movable rod 53 is rotatably connected to the movable blocks 51. The end of the movable rod 53 away from the movable blocks 51 is rotatably connected to the bottom of the buffer shell 4. A damping element is provided on the straight rod 5.

[0033] Specifically, when the protective box 1 lands, the impact force causes the buffer shell 4 to move downwards. At the same time, the two movable rods 53 drive the two moving blocks 51 to move out of phase and stretch the spring 52. This can greatly absorb and weaken the impact force on the protective box 1 when it lands, so as to achieve the function of buffering and protecting the goods inside the protective box 1, thereby greatly reducing the risk of damage to the goods and improving the safety of cargo transportation.

[0034] Both sides of the buffer shell 4 are fixedly connected to sliders 41, and both sides of the inner wall of the base 3 are provided with sliding grooves 42, and the sliders 41 are longitudinally slidably connected in the sliding grooves 42.

[0035] Specifically, the slider 41 and the groove 42 are designed to guide the buffer shell 4 so that it does not deviate when it moves up and down to buffer.

[0036] The damping component includes a buffer airbag 6 sleeved on the straight rod 5. The two ends of the buffer airbag 6 are fixedly connected to the inner wall of the base 3 and the surface of the moving block 51, respectively. The buffer airbag 6 is connected to an air inlet pipe 61 and an exhaust pipe 62. Both the air inlet pipe 61 and the exhaust pipe 62 extend to the outside of the base 3. Both the air inlet pipe 61 and the exhaust pipe 62 are equipped with one-way valves.

[0037] Specifically, when the two moving blocks 51 move apart, they will also compress the buffer airbag 6, causing the air inside the buffer airbag 6 to be gradually discharged through the exhaust pipe 62. When the spring 52 returns to its original position, it will drive the moving blocks 51 and the buffer airbag 6 to return to their original position together, allowing outside air to enter the buffer airbag 6 through the air intake pipe 61. Through the expansion and contraction of the buffer airbag 6, the impact force received by the protective box 1 when it lands can be further weakened, thereby improving the buffer protection effect on the cargo. It can also provide motion damping force for the moving blocks 51, thereby quickly calming unnecessary movement in the structure and suppressing the occurrence of resonance effect, which helps to improve the stability of the protective structure.

[0038] In addition, the two one-way valves enable the intake pipe 61 to be used for one-way air intake only, and the exhaust pipe 62 to be used for one-way exhaust only.

[0039] The straight rod 5 has a square design, and the moving block 51 is slidably connected to the straight rod 5.

[0040] Specifically, this design improves the stability of the moving block 51, allowing it to move laterally only along the surface of the straight rod 5.

[0041] A filter element 63 is fixedly installed on the air intake pipe 61, and the filter element 63 is arranged at the air intake port of the air intake pipe 61.

[0042] Specifically, the filter element 63 can filter the air entering the buffer airbag 6, preventing external dust and impurities from entering the buffer airbag 6 with the air.

[0043] The push-pull part includes a guide sleeve 21 fixedly connected to the protective door 2, a fixed rod 22 slidably connected to the guide sleeve 21, and a locking element provided on the fixed rod 22.

[0044] Specifically, in use, the guide sleeve 21, the fixing rod 22, and the locking element facilitate the opening and closing of the protective door 2, while also ensuring the stability of the protective door 2 when closed, thereby protecting the goods inside the protective box 1.

[0045] The locking component includes a limiting frame 23 fixedly connected to the protective box 1, and a fixing rod 22 inserted into the limiting frame 23. The surface of the protective door 2 is fixedly connected to a buckle 24, and the surface of the fixing rod 22 is fixedly connected to a locking plate 25, which is engaged with the buckle 24.

[0046] Specifically, by pushing the locking plate 25 upward, the locking plate 25 is disengaged from the buckle 24, and at the same time, the fixing rod 22 is disengaged from the limiting frame 23, thereby releasing the fixation of the protective door 2. Then, the locking plate 25 is rotated and pulled, so that the protective door 2 can be opened quickly.

[0047] Working principle: During use, the safety protection structure for this lifting machinery, through the cooperation of the protective box 1 and the protective door 2, can form a closed space to wrap and protect the goods, thereby greatly reducing the risk of goods falling during transportation;

[0048] Furthermore, when the protective box 1 lands down following the hook of the crane, the impact force of the fall causes the buffer shell 4 to move downward. At the same time, the two movable rods 53 drive the two moving blocks 51 to move away from each other and stretch the spring 52. The spring 52 can absorb and weaken the impact force when the protective box 1 lands, so as to achieve the function of buffering and protecting the goods inside the protective box 1, thereby greatly reducing the risk of damage to the goods and improving the safety of cargo transportation.

[0049] In addition, when the two moving blocks 51 move apart, they will compress the buffer airbag 6, causing the air inside the buffer airbag 6 to be gradually discharged through the exhaust pipe 62. When the spring 52 returns to its original position, it will drive the moving blocks 51 and the buffer airbag 6 to return to their original position together, allowing outside air to enter the buffer airbag 6 through the air intake pipe 61. Through the expansion and contraction of the buffer airbag 6, the impact force on the protective box 1 when it lands can be further weakened, thereby improving the buffer protection effect on the cargo. It can also provide motion damping force for the moving blocks 51, thereby quickly calming unnecessary movement in the structure and suppressing the occurrence of resonance effect, which helps to improve the overall stability of the protective structure.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
