Description

Technical Field

[0001] The invention relates to the field of leveling systems, in particular to a leveling leg foot structure with built-in pads. Background Art

[0002] In the field of construction vehicles, due to the large loads they carry, they often need to be equipped with a leveling system. Leveling systems typically consist of four leveling legs and a control system, and many mature products are already available on the market.

[0003] The leveling legs in the leveling system of engineering vehicles usually need to be used with skids, such as Figure 1 As shown, when leveling on unpaved roads requires skids, they become essential tools for construction vehicles. Skids are typically made of logs with steel edging, though cast aluminum versions are also available. Standardized skids are available in the market, with common sizes including: 250mm (length) × 250mm (width) × 80mm (thickness) and 250mm (length) × 250mm (width) × 100mm (thickness). Skids are typically stored in a container within the construction vehicle. When needed, the operator removes the skids from the container and places them directly below the corresponding leveling legs. Only after the skids are in place can the operator begin leveling. When the construction vehicle leaves the site, the operator activates the leveling system, returns the legs to their original position, and then returns each skid to the skid storage box. Skids typically weigh around 5 kg, requiring the operator to constantly move skids in and out of the storage box, which can sometimes lead to skids being missed. Engineering vehicle operators usually want the skids to be as large as possible, with better load-bearing capacity and lighter weight, which is a conflicting requirement. If the skids are larger, they will require larger skid storage boxes, which will be heavier and not conducive to operator use. Summary of the Invention

[0004] The purpose of the present invention is to provide a leveling leg foot structure with built-in pads to address the above-mentioned shortcomings, thereby solving the problem in the prior art that the pads of the leveling legs are inconvenient to move and transport, which is not conducive to use by operators.

[0005] The present invention is achieved through the following solutions:

[0006] A leveling leg foot structure with built-in pads, comprising a foot plate, a pad and a connecting rope; a hinged structure is provided between the foot plate and the pad, and the pad is provided with a quick-connect structure for quickly connecting or disassembling with the leveling leg; one end of the connecting rope is connected to the main body of the balancing leg telescopic member, and the other end is connected to the pad, and the foot plate is connected to the telescopic part of the balancing leg telescopic member; the posture after the pad is separated from the leveling leg is a first posture; the telescopic member is actuated after the pad is separated from the leveling leg, so that the pad automatically forms a second posture in close contact with the foot plate under the action of the connecting rope.

[0007] Based on the above-mentioned leveling leg foot structure with built-in pads, the articulated structure includes a steering hinge, a first connecting ear and a second connecting ear, the first connecting ear is arranged on the pad, the second connecting ear is arranged on the foot plate, the end of the first connecting ear away from the pad is provided with a first connecting hole connected to the steering hinge, and the end of the second connecting ear away from the foot plate is provided with a second connecting hole connected to the steering hinge; the steering hinge is hinged to the first connecting hole and the second connecting hole respectively.

[0008] Based on the above-mentioned leveling leg foot structure with built-in pads, the steering hinge is an arc-shaped structure, and the bending direction of the steering hinge is the same as the movement direction from the first posture to the second posture.

[0009] Based on the above-mentioned leveling leg foot structure with built-in pads, at least two hinge structures are provided on the contact end surfaces of the pads and the footboards.

[0010] Based on the above-mentioned leveling leg foot structure with built-in pads, the quick-connect structure includes a first connecting seat and a second connecting seat, the first connecting seat is arranged on the main body of the balancing leg telescopic component, and the second connecting seat is arranged on the end face of the pad opposite to the first connecting ear, the first connecting seat is provided with a hook, and the second connecting seat is provided with a hanging rod matching the hook.

[0011] Based on the above-mentioned leveling leg foot structure with built-in pads, at least two of the second connecting seats and hooks are provided on the pads.

[0012] Based on the above-mentioned leveling leg foot structure with built-in pads, a first hanging point connected to the connecting rope is provided on the pad, and the first hanging point is arranged on the side wall of the pad between the first connecting ear and the second connecting seat; a second hanging point connected to the connecting rope is provided on the main body of the balancing leg telescopic member, and the second hanging point is arranged on the end face of the main body of the balancing leg telescopic member away from the first connecting seat.

[0013] Based on the above-mentioned leveling leg foot structure with built-in pads, when the pads are hung on the balancing leg, the bottom surface of the pads will contact the balancing leg, and the first hanging point is set on the end of the side away from the bottom surface.

[0014] Based on the above-mentioned leveling leg foot structure with built-in pads, the connecting rope, the first hanging point and the second hanging point are symmetrically arranged along the central axis of the pads.

[0015] Based on the above-mentioned leveling leg foot structure with built-in pads, an auxiliary pull ring is provided on at least one side surface of the pads.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. In this solution, since the skids are provided with a quick-connect structure for quick connection or disassembly with the leveling legs, when the skids are needed, it is only necessary to manually change the state of the skids to achieve quick disassembly. The skids automatically move to a predetermined first posture through the hinge structure, and then the telescopic parts of the leveling legs perform telescopic action, so that the skids are gradually stretched by the joint action of the connecting rope and the telescopic part of the telescopic part to achieve the second posture in which they are firmly in contact with the footboard; in the process of moving from the first posture to the second posture, no manual intervention is required, and the skids are automatically stretched to the predetermined position by relying on the telescopic power of the telescopic part, which greatly reduces the intensity of manual work; manual work only needs to connect and separate the skids with the leveling legs through the quick-connect structure when working

[0018] 2. The present invention utilizes the remaining space of the leveling legs to place large-sized skids. The space here replaces the space of the skid storage box of the engineering vehicle, thereby saving the space on the engineering vehicle.

[0019] 3. The present invention integrates the pads into the leg structure of the leveling legs, thereby avoiding the operation of the engineering vehicle operator to carry the pads, reducing the operator's carrying time, thereby minimizing the preparation time of the leveling system and reducing the labor intensity of the operator.

[0020] 4. The specifications of the structurally integrated skids of the present invention can be up to 400 mm (length) × 300 mm (width) × 100 mm (thickness), or even larger, which is more conducive to leveling the engineering vehicle on uneven roads.

[0021] 5. When the leveling system of the present invention moves into place under the action of the elastic pull rope, the block is located just below the footboard, and the operator does not need to adjust the position of the block, thereby avoiding safety accidents such as the leveling leg footboard deviating from the center of the block when the operator does not place the block properly, causing the leveling leg to tip over.

[0022] 6. When the leveling system of the present invention is in place, the block is located just below the footboard, and the operator does not need to walk around the engineering vehicle to confirm the position of the block, thereby reducing the difficulty of operation for the operator.

[0023] 7. The skids of the present invention are larger than conventional skids, but have the same structure as conventional skids, and do not increase the cost of the skids themselves. The present invention reduces the difficulty and labor intensity of the operator, thereby increasing the added value of the leveling system. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1

[0035] like Figures 2 to 6 As shown, the present invention provides a technical solution:

[0036] A leveling leg foot structure with built-in pads, which at least includes but is not limited to a foot plate 1, a pad 2 and a connecting rope 3; a hinge structure 4 is provided between the foot plate 1 and the pad 2, and a quick-connect structure 5 for quickly connecting or disassembling with the leveling leg is provided on the pad 2; one end of the connecting rope 3 is connected to the main body 6 of the balancing leg telescopic component, and the other end is connected to the pad 2, and the foot plate 1 is connected to the telescopic part 7 of the balancing leg telescopic component; the posture after the pad 2 and the leveling leg are separated is the first posture; the telescopic component is actuated after the pad 2 and the leveling leg are separated, so that the pad 2 automatically forms a second posture in close contact with the foot plate 1 under the action of the connecting rope 3.

[0037] Based on the above structure, since the pad 2 is provided with a quick-connect structure 5 for quickly connecting or disassembling with the leveling leg, when the pad 2 is needed, it is only necessary to manually change the state of the pad 2 to achieve quick disassembly, and the pad 2 automatically moves to the predetermined first posture through the hinge structure 4, and then the leveling leg telescopic member performs a telescopic effect, so that the pad 2 is gradually stretched by the joint action of the connecting rope 3 and the telescopic part 7 of the telescopic member to achieve the second posture of firmly contacting the foot plate 1; in the process of moving from the first posture to the second posture, no manual participation is required, and the pad 2 is automatically stretched to the predetermined position by relying on the telescopic power of the telescopic part 7, which greatly reduces the intensity of manual work; manual work only needs to connect and separate the pad 2 with the leveling leg through the quick-connect structure 5 when working.

[0038] As an example, the hinged structure 4 may include a steering hinge 401, a first connecting ear 402 and a second connecting ear 403, the first connecting ear 402 being arranged on the pad 2, the second connecting ear 403 being arranged on the foot plate 1, the end of the first connecting ear 402 away from the pad 2 being provided with a first connecting hole connected to the steering hinge 401, the end of the second connecting ear away from the foot plate 1 being provided with a second connecting hole connected to the steering hinge 401; the steering hinge 401 is hinged to the first connecting hole and the second connecting hole respectively.

[0039] Based on the above structure, a certain distance can be reserved for the pad 2 and the footboard 1 through the steering hinge 401, so that the pad 2 can completely fit with the bottom of the foot when being pulled, thereby achieving auxiliary support for the foot.

[0040] As an example, the steering hinge 401 may be an arc-shaped structure, and the bending direction of the steering hinge 401 is the same as the movement direction from the first posture to the second posture, so as to ensure that the movement process of the sleeper 2 to the footboard 1 is carried out smoothly.

[0041] As an example, at least two hinge structures 4 are provided on the contact end surfaces of the skid 2 and the footboard 1. This ensures that the skid 2 can run stably in a predetermined direction.

[0042] As an example, the quick-connect structure 5 may include a first connecting seat 501 and a second connecting seat 502, the first connecting seat 501 being arranged on the main body 6 of the balancing leg telescopic component, and the second connecting seat 502 being arranged on the end face of the pad 2 opposite to the first connecting ear 402, the first connecting seat 501 may be provided with a hook 503, and the second connecting seat 502 may be provided with a hanging rod 504 matching the hook 503; the hook 503 can be hung on the hanging rod 504, so that the pad 2 and the main body 6 of the balancing leg telescopic component are connected and fixed.

[0043] Based on the above structure, by setting the hook 503 and the hanging rod 504, the construction requirements and technical difficulty of the operators can be reduced, the overall operation is simple, and the error rate of operation can be reduced. The quick connection structure 5 in this solution can also be other forms of structure, as long as it can quickly fix the pad 2 on the balance leg.

[0044] As an example, at least two second connecting seats 502 and hooks 503 can be provided on the skid 2. This ensures the stability of the hooking.

[0045] As an example, a first hanging point 201 connected to the connecting rope 3 is provided on the pad 2, and the first hanging point 201 is set on the side wall of the pad 2 between the first connecting ear 402 and the second connecting seat 502; a second hanging point 202 connected to the connecting rope 3 is provided on the main body 6 of the balancing leg telescopic component, and the second hanging point 202 is set on the end face of the main body 6 of the balancing leg telescopic component away from the first connecting seat 501.

[0046] Based on the above structure, this solution uses a special setting. After the pad 2 is removed from the balancing leg, the connecting rope 3 can gradually stretch the pad 2 under the power of the telescopic part, and finally stretch it to the second posture in contact with the footboard 1.

[0047] As an example, when the sleeper 2 is hung on the balancing leg, the bottom surface 203 of the sleeper 2 will contact the balancing leg, and the first hanging point 201 is set on the end of the side away from the bottom surface 203.

[0048] Based on the above structure, the first hanging point 201 set at a special position can reduce the error rate when the stretching block 2 is stretched and retracted in the later stage, so that the stretching action can be performed efficiently.

[0049] As an example, the connecting rope 3, the first hanging point 201 and the second hanging point 202 are symmetrically arranged along the central axis of the sleeper 2. How to arrange them can ensure that both sides of the sleeper 2 are pulled synchronously and ensure the stability of the pulling.

[0050] As an example, an auxiliary pull ring 8 may be provided on at least one side of the sleeper 2, and the auxiliary pull ring 8 can facilitate the operator to hold the sleeper 2 and start the disassembly and fixing operations.

[0051] In this solution, in the initial state of the leveling system, the pads 2 are hung on the leveling leg body through the quick-connect structure 5, and the pads 2 are transported together with the leveling leg. The space here replaces the space position of the pad 2 storage box of the engineering vehicle. At the same time, since the pads 2 are placed near the footboard 1, the operator does not need to take the pads 2 from the original pad 2 storage box or put the pads 2 into the pad 2 storage box.

[0052] As an example, the available design specifications of the sleeper 2 are: 300 mm (length) × 300 mm (width) × 100 mm (thickness) or 400 mm (length) × 300 mm (width) × 100 mm (thickness) and the like.

[0053] As an example, the connecting rope 3 can be an elastic drawstring.

[0054] How to use this solution:

[0055] like Figure 3 As shown, when the engineering vehicle needs to be leveled, the operator only needs to push the block 2 upward once, and the block 2 can rotate downward around the second connecting ear 403 on the foot plate 1 to the first posture together with the steering hinge 401 under the action of its own weight.

[0056] The leveling system is generally driven by a motor servo. The foot plate 1 of the leveling leg moves downward under the action of the electric cylinder. Figure 4 As shown, under the action of the elastic pull rope, when the foot plate 1 moves into place, the mat 2 is in a horizontal position (second posture) under the action of the pull rope. Figure 4 It can also be seen that by adjusting the length of the steering hinge 401, the block 2 can be placed exactly below the foot plate 1. The present invention does not require the operator to adjust the position of the block 2, thus avoiding safety accidents such as the leveling leg foot plate 1 deviating from the center of the block 2 when the operator does not place the block 2 properly, causing the leveling leg to fall over.

[0057] When the leveling system needs to be withdrawn, the movement of the pad 2 is opposite to the previous description. The operator only needs to hang the pad on the leveling leg body nearby.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
