Description

Technical Field

[0001] This utility model relates to the field of hoisting and guiding technology, and more specifically, to a hoisting and guiding device for mining shaft construction. Background Technology

[0002] In the construction of mine shafts, hoisting and guiding devices play a crucial role. However, existing hoisting and guiding devices for mine shaft construction have many problems, seriously affecting construction efficiency and safety.

[0003] First, the equipment is difficult to move. Currently, some guiding devices are bulky and heavy, lacking convenient moving mechanisms. When frequent repositioning is needed on the construction site, a significant amount of manpower and resources are required for transport, increasing construction costs and potentially delaying the construction schedule. Even if some devices are equipped with casters, the casters are poorly designed, lacking lifting capabilities, preventing them from detaching from the ground when fixing the device. This results in unstable installation and easy displacement during construction.

[0004] Secondly, the fixing methods are limited and lack stability. Most existing guide devices are fixed using simple bolt connections or welding, which is unsuitable for various geological conditions and wellbore specifications. In complex geological environments, such as soft ground or areas with fractured rock, a single fixing method cannot provide sufficient stability. During hoisting operations, the guide device is prone to swaying, tilting, or even collapse, seriously threatening the lives of construction personnel and potentially damaging the wellbore and hoisting equipment, resulting in significant economic losses.

[0005] In summary, existing hoisting and guiding devices for mine shaft construction have significant shortcomings in terms of equipment movement and fixation, and there is an urgent need for a new guiding device to solve these problems in order to improve the efficiency and safety of mine shaft construction.

[0012] In the preferred embodiment of this utility model, the two first supports are L-shaped and symmetrically arranged, and the two first supports have different lengths.

[0013] In a preferred embodiment of this utility model, a limiting block is fixedly installed at the top of the slide plate. The limiting block is cross-shaped. The top of the support frame is symmetrically provided with sliding holes that match the limiting block. Guide rods are symmetrically fixedly installed on the inner wall of the sliding holes. The limiting block is slidably installed on the guide rods.

[0014] In a preferred embodiment of this utility model, the adjusting assembly includes a second threaded rod, a rotating shaft, and a motor. A strip-shaped cavity is symmetrically arranged within the support frame. The second threaded rod is rotatably mounted between the two sides of the inner wall of the strip-shaped cavity.

[0017] The beneficial effects of this utility model are:

[0018] Convenient and flexible mobility: The device features casters at the bottom of the base, allowing construction workers to easily move the equipment around the construction site. This avoids the difficulties of transporting traditional large equipment, saving significant manpower and time and improving pre-construction preparation efficiency. Furthermore, the unique design incorporates a sliding base plate within a recessed groove, with the casters positioned on the plate. The plate's lifting and lowering is controlled by an electric actuator. Upon reaching the designated construction position, the actuator retracts, raising the base plate and lifting the casters off the ground. This effectively prevents instability caused by the casters, ensuring greater stability and reliability during operation.

[0019] Multiple and Stable Fixing Methods: The diverse fixing methods greatly enhance the stability of the device. First, the positioning plates with positioning holes on both sides of the base can be used with ground nails to fix it to the ground. Whether it is soft soil or hard rock, it can adapt to and provide a reliable foundation fixation, ensuring that the device can be firmly rooted even in complex geological conditions. Second, by rotating the turntable with anti-slip texture, the first threaded rod is rotated, which in turn moves the reinforcement frame to clamp and fix the outside of the well barrel, enhancing the tightness of the connection between the device and the well barrel and preventing the device from shifting on the well barrel surface. Third, the extrusion plate is driven by the adjustment component to clamp the inner wall of the well barrel. The motor drives the second threaded rod to rotate, and the two second threaded rods rotate synchronously through the rotating shaft. The slider drives the limit block and the sliding plate to move, thereby precisely controlling the position of the extrusion plate and achieving a stable clamping of the inner wall of the well barrel. This double clamping design enhances the fixing effect between the device and the well barrel from multiple dimensions. During hoisting operations, it can effectively resist various external interferences, greatly improve the overall stability, and ensure construction safety and normal equipment operation.

[0020] Wide applicability and efficient construction assistance: This guiding device, with its multiple adjustment and fixing functions, can adapt to the construction needs of well casings of different specifications. Whether the well casing is large or small in diameter, the position of the clamping plate can be flexibly adjusted via the adjusting components, and the clamping range on the outside of the well casing can be adjusted via the reinforcing frame to ensure a tight fit. In actual construction, the coordinated design of the guide hole and guide wheel provides precise guidance for the hoisting rope, reduces rope wear, improves the accuracy and safety of hoisting, reduces construction risks, accelerates construction progress, and effectively improves construction efficiency.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Please see Figures 1-3 This utility model provides a technical solution: a hoisting and guiding device for mining shaft construction, comprising a U-shaped support frame 110, a first bracket 111 symmetrically fixedly installed at the top of the inner wall of the support frame 110, a guide wheel 112 rotatably installed on the first bracket 111, a base 120 symmetrically fixedly installed at the bottom of the support frame 110, a universal wheel 121 installed at the bottom of the base 120, positioning plates 122 with positioning holes symmetrically installed on both sides of the base 120, a first threaded rod 130 symmetrically rotatably installed on both sides of the support frame 110, a reinforcing frame 131 threadedly installed on the first threaded rod 130, one end of the reinforcing frame 131 slidingly passing through the support frame 110 and extending to the outside, a sliding plate 140 symmetrically slidably installed at the top of the inner wall of the support frame 110, a pressing plate 141 slidably sleeved at the bottom of the sliding plate 140, and an adjustment component installed on the sliding plate 140.

[0030] In some specific implementations, the base 120 has a groove at its bottom end, and a base plate 123 is slidably mounted on the inner wall of the groove. Universal wheels 121 are symmetrically fixedly mounted on the bottom end of the base plate 123. Square holes are provided on both sides of the first bracket 111, and an electric push rod 124 is fixedly mounted on the inner wall of each hole. The output end of the electric push rod 124 passes through the first bracket 111 and the base 120 and is fixedly connected to the top of the base plate 123. A limiting frame is fixedly mounted on the bottom end of the inner wall of the groove, and a buffer strip is installed on the top of the limiting frame. When the electric push rod 124 extends, it can push the base plate 123 down, allowing the universal wheels 121 to contact the ground, facilitating device movement. When the electric push rod 124 retracts, it can lift the base plate 123 up, allowing the universal wheels 121 to leave the ground, preventing the universal wheels 121 from affecting the stability of the device. The limiting frame and buffer strip at the bottom end of the inner wall of the groove prevent the base plate 123 from sliding excessively, protecting the electric push rod 124 and providing cushioning, thus extending the service life of the device.

[0031] In some specific implementation schemes, a turntable 132 is fixedly mounted on one end of the first threaded rod 130, and the outer side of the turntable 132 is provided with anti-slip texture. When the turntable 132 is rotated, the friction between the operator's hand and the turntable 132 increases, making operation more labor-saving and less prone to slipping. This allows for convenient and quick rotation of the first threaded rod 130, thereby efficiently adjusting the position of the reinforcing frame 131 and achieving rapid clamping and fixing of the well shaft.

[0032] In some specific implementation schemes, two reinforcing frames 131 are provided with arc-shaped grooves at one end, and anti-slip pads are installed on the inner walls of the arc-shaped grooves. The first support 111 has sliding holes on both sides that match the reinforcing frames 131, and the electric push rod 124 is located inside the reinforcing frame 131. The arc-shaped grooves and anti-slip pads design better conform to the outer surface of the well casing, increasing the friction between the frame and the well casing and improving the clamping stability of the reinforcing frame 131. Even if vibration occurs during hoisting, the well casing is less likely to slip off the reinforcing frame 131, ensuring construction safety. The sliding holes on both sides of the first support 111 match the reinforcing frame 131, providing guidance for the movement of the reinforcing frame 131, making its movement smoother and more precise.

[0033] In some specific implementation schemes, a guide hole 113 is provided at the top of the support frame 110. An opening is provided on one side of the guide hole 113. Both the top and bottom ends of the guide hole 113 are arc-shaped, and the guide hole 113 is located at the center of the top of the support frame 110. The arc shape reduces rope wear during the guiding process, extending the rope's service life. The guide hole 113's location at the center of the top of the support frame 110 ensures uniform force distribution on the rope during the guiding process, making the hoisting operation more stable and safer.

[0034] In some specific implementation schemes, the two first supports 111 are L-shaped and symmetrically arranged, with different lengths. This better adapts to hoisting requirements at different angles and positions, optimizes the guiding effect on the hoisting ropes, and improves the accuracy of hoisting operations.

[0035] Please see Figure 4 and Figure 5 A limiting block 150 is fixedly installed at the top of the skateboard 140. The limiting block 150 is cross-shaped. The top of the support frame 110 is symmetrically provided with sliding holes that match the limiting block 150. Guide rods 151 are symmetrically fixedly installed on the inner wall of the sliding holes. The limiting block 150 is slidably installed on the guide rods 151. This ensures that it can only slide along the direction of the guide rods 151, thus guaranteeing the stability and accuracy of the movement of the skateboard 140. When adjusting the position of the extrusion plate 141, the inner wall of the wellbore can be clamped and fixed more accurately, preventing the extrusion plate 141 from shifting and affecting the fixing effect. The adjustment assembly includes a second threaded rod 152, a rotating shaft 153, and a motor 154. A strip-shaped cavity is symmetrically arranged inside the support frame 110. The second threaded rod 152 is rotatably installed between the two sides of the inner wall of the strip-shaped cavity. A slider 155 is threaded onto the second threaded rod 152, and the slider 155 is fixedly connected to one end of the limiting block 150. Two second threaded rods 152 are symmetrically arranged and the rotating shaft 153 is fixedly installed between them. The motor 154 is fixedly installed on the outside of the support frame 110. The output end of the motor 154 passes through one side of the support frame 110 and is fixedly connected to one end of the adjacent second threaded rod 152. The strip-shaped cavity communicates with the sliding hole, and the slider 155 is slidably connected to the inner wall of the strip-shaped cavity. This automated adjustment method is more efficient and accurate than traditional manual adjustment, and can quickly adapt to the fixing requirements of different wellbore inner diameters, improving construction efficiency. The strip cavity is connected to the sliding hole, and the slider 155 is slidably connected to the inner wall of the strip cavity, providing a stable track for the movement of the slider 155 and ensuring the smoothness of the adjustment process.

[0036] In some specific implementations, the two extrusion plates 141 are arranged in an arc shape on the side furthest from each other. The bottom end of the slide plate 140 has a guide groove that matches the extrusion plates 141. A support rod 142 is fixedly installed at the top of the inner wall of the guide groove. The extrusion plates 141 are slidably mounted on the support rod 142. A circular plate is fixedly installed at the bottom end of the support rod 142. The top end of the extrusion plates 141 has a circular groove that matches the circular plate. The extrusion plates 141 are slidably connected to the inner wall of the guide groove. The diameter of the circular plate is larger than the diameter of the support rod 142. The top end of the support rod 142 slides through the top end of the extrusion plates 141 and extends into the circular groove. This makes the extrusion plates 141 more stable during sliding and less prone to shaking. The larger diameter of the circular plate than the support rod 142 prevents the extrusion plates 141 from falling off the support rod 142, ensuring the normal operation of the device.

[0037] In some specific implementation schemes, an iron plate 143 is fixedly installed at the bottom of the extrusion plate 141, and a magnetic ring that cooperates with the iron plate 143 is installed at the bottom of the sliding plate 140, which facilitates the storage and organization of the device. It also serves a certain positioning function when installing and adjusting the extrusion plate 141, making it convenient for construction personnel to operate.

[0038] Working principle: In use, the equipment is pushed to the guide position via the casters 121. The electric push rod 124 is activated to retract, causing the casters 121 on the base plate 123 to move until they are off the ground. The equipment is then fixed to the ground by engaging with the ground nails through the positioning holes on the positioning plate 122. The turntable 132 is rotated, causing the first threaded rod 130 to rotate. The rotation of the first threaded rod 130 causes the reinforcing frame 131 to move and clamp and fix the outside of the well barrel. Finally, the extrusion plate 141 is pulled down into the well barrel. The motor 154 is activated, causing the second threaded rod 152 to rotate. The rotation of the second threaded rod 152 drives another second threaded rod 152 to rotate synchronously via the rotating shaft 153. This causes the limit block 150 to move relative to the slider 155. The movement of the limit block 150 causes the extrusion plate 141 to move via the sliding plate 140, clamping and fixing the inner wall of the well barrel. Finally, the tensioner is stretched through the guide hole 113 and the guide wheel 112 for guidance.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
