Description

Technical Field

[0001] This utility model belongs to the technical field of mine transport vehicles, specifically a vertical shaft hydraulic lifting vehicle. Background Technology

[0002] In coal mine transportation operations, critical materials required for tunneling support, such as extra-long anchor belts, steel beams, and U-shaped canopies, vary in size and specifications. Traditional transportation methods rely on inclined shafts, requiring materials to be first transferred by surface trucks to the mine's material yard, and then transported in sections via three inclined shafts and three horizontal main roadways. This model has significant drawbacks: prominent safety hazards, frequent inclined shaft hoisting easily leading to vehicle derailments, and the continuous operation of detaching and attaching components in the horizontal main roadways easily causing personnel injuries; low efficiency, long transportation distances, numerous steps, time-consuming and labor-intensive, and requiring a large number of personnel; and production constraints, with delayed material transportation causing tunneling at the face to stop due to unsupported roofs, endangering construction safety.

[0003] In coal mine hoisting and transportation operations, a vertical shaft is also available. The transportation vehicle in the shaft is a cage, a type of mine hoisting container used to transport personnel, ore, equipment, materials, etc. It can generally carry several tons and serves a similar purpose to an elevator. However, excessively long materials cannot be directly lowered through the vertical shaft due to the fixed size limitations of the cage.

[0004] Although inclined shaft transportation is the only feasible route, its high risk and low efficiency have long constrained safe production in mines. Existing technologies lack flexible transportation solutions for irregular and extra-long materials in vertical shaft scenarios. There is an urgent need for a device that can dynamically adjust the spatial posture of materials to adapt extra-long materials to the cage structure, thereby avoiding the risks of inclined shaft transportation, shortening the transportation cycle, and ensuring the continuity of tunneling operations. Utility Model Content

[0005] To address the problem that excessively long materials cannot be easily adjusted in terms of spatial orientation, thus preventing them from entering the cage of a vertical shaft for transfer and resulting in high risks and long cycles due to the reliance on inclined shafts for transportation, this utility model provides a vertical shaft hydraulic lifting vehicle.

[0006] This utility model is achieved through the following technical solution:

[0007] A vertical shaft hydraulic lifting platform includes a flatbed truck, on which a fixed frame, a tripod assembly, and a support frame are sequentially arranged. The fixed frame is horizontally positioned at one end of the flatbed truck, and the support frame is vertically positioned at the other end of the flatbed truck. The height of the support frame's contact point with the material is greater than the height of the fixed frame's contact point with the material. The tripod assembly includes two tripod bodies arranged in parallel and respectively positioned on both sides of the length direction of the flatbed truck. A sliding lifting channel steel is provided between the two tripod bodies. A hydraulic cylinder is connected between the lifting channel steel and the flatbed truck, and the hydraulic cylinder is connected to a hydraulic pump capable of driving the hydraulic cylinder to extend and retract via a pipeline.

[0008] By using the height difference between the fixed frame and the support frame to form a material tilting support foundation, and with the hydraulic cylinder-driven lifting channel steel sliding on the triangular frame assembly, the tilt angle and spatial posture of ultra-long materials can be flexibly adjusted. By adjusting the posture of ultra-long materials, the space of the cage can be adapted, breaking through the limitation of the fixed size of the vertical shaft cage, realizing the transportation of materials through the vertical shaft, reducing transportation risks, shortening the transportation cycle, and improving the efficiency of tunneling operations.

[0009] A further improvement of this utility model is that the aforementioned tripod body includes a first inclined support leg and a second inclined support leg. Both the first and second inclined support legs are U-shaped channel steel structures, and the openings of the channel steel of the two first and two second inclined support legs are arranged opposite to each other. The two ends of the lifting channel steel extend into the openings of the two second inclined support legs. The U-shaped channel steel structure of the inclined support legs forms a guide rail, and the two ends of the lifting channel steel slide within the openings, ensuring the stability and accuracy of material support during adjustment, avoiding deviation or swaying, and guaranteeing safe and stable posture adjustment for ultra-long materials.

[0010] A further improvement of this utility model is that the aforementioned inclined support leg two is evenly distributed with locking pin holes, and a pin capable of supporting the lifting channel steel can be inserted into the locking pin holes. Through the cooperation of the locking pin holes and the pins, mechanical locking is achieved after the lifting channel steel is adjusted into position, forming a double fixation with the hydraulic cylinder drive, thereby enhancing the stability of posture maintenance.

[0011] A further improvement of this invention is that the length of the second inclined support leg is greater than the length of the first inclined support leg, and the top of the second inclined support leg is located above the connection point between the second and the first inclined support leg. The longer length and higher top of the second inclined support leg provide a greater sliding stroke for the lifting channel steel, allowing it to accommodate more extra-long materials of different lengths and tilt requirements.

[0012] A further improvement of this invention is that the angle α between the second inclined support leg and the flatbed is less than 90° and greater than the angle β between the first inclined support leg and the flatbed. By optimizing the force-bearing structure of the tripod assembly through the angle difference, the larger angle of the second inclined support leg enhances the vertical support force on the lifting channel steel, reduces the risk of structural deformation, ensures structural stability when transporting overweight and overlength materials, extends the service life of the equipment, and reduces maintenance costs.

[0013] A further improvement of this invention is that reinforcing ribs are connected between the two inclined support legs and between the two inclined support legs. These reinforcing ribs enhance the overall rigidity of the tripod assembly, preventing the inclined support legs from shifting due to uneven stress, improving the structure's resistance to deformation, reducing the decrease in posture adjustment accuracy caused by frame deformation, and improving equipment reliability.

[0014] A further improvement of this invention is that the aforementioned fixing frame has an overall U-shaped structure, and the opening of the fixing frame faces the supporting frame. The U-shaped structure can limit the lower end of the extra-long material from three directions in the plane, and the opening facing the supporting frame facilitates the positioning of the material during loading and unloading, avoids posture deviation caused by shaking, and reduces the operational difficulty during loading and unloading.

[0015] A further improvement of this invention is that a portion of the aforementioned fixing frame extends outside the flatbed trailer, and the flatbed trailer is provided with a bottom support plate that can seal the fixing frame. The extension of the fixing frame to the outside can accommodate materials of excessive length, compensating for the insufficient length of existing flatbed trailers. The bottom support plate, once sealed, forms a complete support surface, preventing the material ends from sagging, ensuring balanced overall force distribution on the material, and avoiding structural damage or imbalance caused by the ends being suspended.

[0016] A further improvement of this invention is that the flatbed truck is also equipped with a dividing column, which is located near one end of the fixed frame and corresponds to the midpoint of the lifting channel steel. The dividing column can separate multiple parallel transported materials, preventing them from colliding with each other, increasing the single transport capacity, and enabling the simultaneous transport of multiple extra-long materials; at the same time, to prevent the extra-long materials from shifting, they can be tied to the dividing column with ropes.

[0017] A further improvement of this invention is that two fixing frames are provided, one on each side of the partition column. The dual fixing frames, in conjunction with the partition column, allow for independent fixing of materials on both sides, enhancing stability and controllability during multi-material transportation.

[0018] As can be seen from the above technical solution, the beneficial effects of this utility model are: by forming a material tilting support foundation through the height difference between the fixed frame and the support frame, and by sliding the lifting channel steel driven by the hydraulic cylinder on the triangular frame assembly, the tilt angle and spatial posture of the ultra-long material can be flexibly adjusted. By adjusting the posture of the ultra-long material, the space of the cage can be adapted, breaking through the limitation of the fixed size of the vertical shaft cage, realizing the transportation of materials through the vertical shaft, reducing transportation risks, shortening the transportation cycle, and improving the efficiency of tunneling operations.

Detailed Implementation

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] like Figures 1-3As shown, this utility model discloses a vertical shaft hydraulic lifting vehicle, including a flatbed truck 10. The flatbed truck 10 is sequentially provided with a fixed frame 40, a triangular frame assembly, and a support frame 20. The fixed frame 40 is horizontally arranged at one end of the flatbed truck 10, and the support frame 20 is vertically arranged at the other end of the flatbed truck 10. The height of the contact point between the support frame 20 and the material is greater than the height of the contact point between the fixed frame 40 and the material. The triangular frame assembly includes two triangular frame bodies 30, which are arranged in parallel and respectively located on both sides of the length direction of the flatbed truck 10. A sliding lifting channel steel 34 is provided between the two triangular frame bodies 30. A hydraulic cylinder 50 is connected between the lifting channel steel 34 and the flatbed truck 10. The hydraulic cylinder 50 is connected to a hydraulic pump that can drive the hydraulic cylinder 50 to extend and retract through a pipeline.

[0026] The material tilting support foundation is formed by the height difference between the fixed frame 40 and the support frame 20. The lifting channel steel 34 driven by the hydraulic cylinder 50 slides on the triangular frame assembly, which can flexibly adjust the tilt angle and spatial posture of the ultra-long material. By adjusting the posture of the ultra-long material, it can adapt to the cage space, break through the limitation of the fixed size of the vertical shaft cage, realize the transportation of materials through the vertical shaft, reduce transportation risks, shorten the transportation cycle, and improve the efficiency of tunneling operations.

[0027] One end of the hydraulic cylinder 50 is hinged to the flatbed trolley 10, and the other end of the hydraulic cylinder 50 is hinged to the lifting channel steel 34. In order to achieve stable movement of the lifting channel steel 34 along the two triangular frame bodies 30, at least two hydraulic cylinders 50 can be provided, and the at least two hydraulic cylinders 50 are evenly distributed along the length direction of the lifting channel steel 34.

[0028] The tripod body 30 includes a first inclined support leg 31 and a second inclined support leg 32. Both the first inclined support leg 31 and the second inclined support leg 32 are U-shaped channel steel structures, and the openings of the channel steel of the two first inclined support legs 31 and the two second inclined support legs 32 are arranged in opposite directions. The two ends of the lifting channel steel 34 extend into the openings of the channel steel of the two second inclined support legs 32, respectively. The U-shaped channel steel structure of the inclined support legs forms a guide rail, and the two ends of the lifting channel steel 34 slide within the openings, ensuring the stability and accuracy of material support during adjustment, avoiding deviation or shaking, and ensuring safe and stable posture adjustment of ultra-long materials.

[0029] The second inclined support leg 32 is evenly distributed with locking pin holes 321, and a pin 322 capable of supporting the lifting channel steel 34 can be inserted into the locking pin holes 321. Through the cooperation of the locking pin holes 321 and the pins 322, mechanical locking is achieved after the lifting channel steel 34 is adjusted into place, forming a double fixation with the hydraulic cylinder 50 drive, enhancing the stability of the posture maintenance.

[0030] A hydraulic pump is provided on one side of the hydraulic cylinder 50 to provide power and is connected to it through a pipeline. When the lifting channel steel 34 is raised to a suitable height, the lifting channel steel 34 is supported by the engagement of the pin 322 with the locking pin hole 321 at the appropriate height. At this time, the hydraulic pump stops supplying fluid to the hydraulic cylinder 50.

[0031] The length of the second inclined support leg 32 is greater than the length of the first inclined support leg 31, and the top of the second inclined support leg 32 is above the connection point between the second inclined support leg 32 and the first inclined support leg 31. The longer length and higher top position of the second inclined support leg 32 provide a greater sliding stroke for the lifting channel steel 34, and can adapt to more extra-long materials with different lengths and different tilt requirements.

[0032] The angle α between the second inclined support leg 32 and the flatbed trolley 10 is less than 90° and greater than the angle β between the first inclined support leg 31 and the flatbed trolley 10. By optimizing the stress structure of the tripod assembly through the angle difference, the larger angle of the second inclined support leg 32 can enhance the vertical support force on the lifting channel steel 34, reduce the risk of structural deformation, ensure structural stability when transporting overweight and overlength materials, extend the service life of the equipment, and reduce maintenance costs.

[0033] Reinforcing ribs 33 connect the two diagonal support legs 31 and the two diagonal support legs 32. The reinforcing ribs 33 enhance the overall rigidity of the tripod assembly, prevent the diagonal support legs from shifting due to uneven force on both sides, improve the structure's resistance to deformation, reduce the problem of decreased posture adjustment accuracy caused by frame deformation, and improve the reliability of the equipment.

[0034] The fixing frame 40 has an overall U-shaped structure, and the opening of the fixing frame 40 faces the supporting frame 20. The U-shaped structure can limit the lower end of the extra-long material from three directions in the plane. The opening facing the supporting frame 20 facilitates the positioning of the material during loading and unloading, avoids posture deviation caused by shaking, and reduces the difficulty of operation during loading and unloading.

[0035] A portion of the fixing frame 40 extends outside the flatbed 10, and the flatbed 10 is provided with a bottom support plate 41 that can block the fixing frame 40. The extension of the fixing frame 40 to the outside can accommodate materials with excessive length, making up for the problem of insufficient length of the existing flatbed 10. After the bottom support plate 41 is blocked, it forms a complete support surface, preventing the end of the material from sagging, ensuring that the overall force on the material is balanced, and avoiding structural damage or posture imbalance caused by the end being suspended.

[0036] The flatbed trolley 10 is also equipped with a dividing column 42, which is located near one end of the fixed frame 40 and corresponds to the midpoint of the lifting channel steel 34. The dividing column 42 can separate multiple materials being transported in parallel, preventing them from colliding with each other, increasing the amount of material transported at one time, and enabling the simultaneous transport of multiple extra-long materials. At the same time, to prevent the extra-long materials from shifting, they can be tied to the dividing column 42 with ropes.

[0037] Two fixing frames 40 are provided, one on each side of the dividing column 42. The two fixing frames 40, together with the dividing column 42, can independently fix the materials on both sides, enhancing the stability and controllability during the transportation of multiple materials.

[0038] The lifting channel steel 34 has at least one dividing protrusion 35 in the middle, which can be used to divide the extra-long material and form an auxiliary fixation.

[0039] The support frame 20 has an overall U-shaped structure. The U-shaped support frame 20 is welded from channel steel or right-angle bent plates, which is convenient to obtain materials and easy to assemble.

[0040] Both ends of the flatbed 10 are equipped with traction frames 11 to facilitate traction and pushing / pulling of the flatbed 10.

[0041] In summary, the working principle of this device is as follows: the fixed frame 40 provides support and limit for one end of the extra-long material, the support frame 20 supports the other end of the extra-long material, and the triangular frame assembly in the middle and the sliding lifting channel steel 34 on it provide auxiliary support for the middle section of the extra-long material, thereby forming a three-point support for adjusting the extra-long material after tilting.

[0042] The method of using this device is as follows: First, transfer the extra-long material to the flatbed trolley 10. The lower end of the extra-long material abuts against the fixed frame 40, and the higher end of the extra-long material presses against the support frame 20. The lifting channel steel 34 between the two inclined support legs 32 supports the middle section of the extra-long material under the action of the hydraulic cylinder 50. After the lifting channel steel 34 and the extra-long material are in stable contact, insert the pin 322 into the locking pin hole 321 at the appropriate height to complete the support of the lifting channel steel 34. Finally, the lower end of the extra-long material can be tied and fixed to the dividing column 42 with ropes, and the higher end of the extra-long material can be tied and fixed to the crossbeam of the support frame 20.

[0043] When the extra-long material enters the cage, the lifting channel steel 34 can be raised and lowered again according to the actual situation so that the higher end of the extra-long material can smoothly enter the cage. At this time, the support frame 20 may not necessarily contact the extra-long material. The higher end of the extra-long material can abut against the inner wall of the cage to form three-point support.

[0044] To ensure the safe transport of oversized materials, ropes can be used to initially secure the materials when they are transferred to the flatbed truck 10. If the posture of the oversized materials needs to be adjusted when they enter the cage, the ropes can be temporarily untied, and the materials will be finally secured after entering the cage.

[0045] The hydraulic lifting vehicle for vertical shafts described in this utility model forms a material tilting support foundation through the height difference between the fixed frame and the support frame. In conjunction with the lifting channel steel driven by the hydraulic cylinder sliding on the triangular frame assembly, the tilt angle and spatial posture of ultra-long materials can be flexibly adjusted. By adjusting the posture of ultra-long materials, the vehicle can adapt to the space of the cage, breaking through the limitation of the fixed size of the vertical shaft cage, realizing the transportation of materials through the vertical shaft, reducing transportation risks, shortening the transportation cycle, and improving the efficiency of tunneling operations.

[0046] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
