[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] like Figures 1 to 8 As shown, the present invention provides a chute hoisting device, which includes a base 10, a pillar 20, a connecting beam 30, an adjusting assembly 40 and a grabbing assembly 50. The base 10 is movably arranged on the chute 01. The pillar 20 has a connecting end 201 and a lifting end 202 that are arranged opposite to each other, the connecting end 201 is arranged on the base 10, and the height of the lifting end 202 relative to the connecting end 201 is adjustable. One end of the connecting beam 30 is movably arranged on the lifting end 202. The adjusting assembly 40 is arranged between the lifting end 202 and the connecting beam 30, and the adjusting assembly 40 is used to adjust the height between the connecting beam 30 and the pillar 20. The grabbing assembly 50 is arranged at the other end of the connecting beam 30, and the grabbing assembly 50 is used to grab the chute to be installed.

[0047] Applying the technical solution of the present invention, the chute hoisting device includes a base 10, a pillar 20, a connecting beam 30, an adjusting assembly 40 and a grabbing assembly 50. The base 10 is movably arranged on the chute 01, and the pillar 20 is a telescopic structure, including a connecting end 201 and a lifting end 202. The connecting end 201 is connected to the base 10, and the lifting end 202 is connected to the connecting end 201 and can be adjusted in height along the axis direction of the pillar 20, so as to adjust the height of the entire pillar 20 so as to be suitable for lanes of different heights. The adjusting assembly 40 is arranged between the lifting end 202 of the pillar 20 and the connecting beam 30, and is used to adjust the positional relationship between the connecting beam 30 and the pillar 20 to adapt to the installation requirements of the chute 01 of different heights. One end of the connecting beam 30 is connected to the lifting end 202, and the other end is connected to the grabbing assembly 50. The grabbing assembly 50 is used to grab the chute to be installed and dock and assemble with the chute 01 installed below the base 10. The grab assembly 50 grabs the chute 01 in a non-chain manner, thereby improving the stability of the chute 01 during the lifting process.

[0048] Specifically, when the chute lifting device needs to work, the base 10 is first placed on the chute 01, and the lifting end 202 is lowered to the lowest position so that the chute lifting device can enter the tunnel smoothly. After entering the tunnel, the base 10 moves on the chute 01 to adjust the position of the chute lifting device. Then, the lifting end 202 and the adjustment component 40 work together to adjust the lifting of the support 20 so that the connecting beam 30 is at an appropriate working height. Finally, the grabbing component 50 grabs the chute to be installed, and by adjusting the orientation of the chute to be installed, the chute 01 is accurately lifted and installed.

[0049] like Figure 4 As shown, the pillar 20 includes a column 21, a sleeve 22 and a lifting member 23. The bottom of the column 21 forms a connection end 201, and the column 21 has a mounting cavity 211 and an opening 212, the opening 212 is connected to the mounting cavity 211, and the opening 212 is located at the top of the column 21; the sleeve 22 is sleeved on the column 21, and the end of the sleeve 22 away from the column 21 forms a lifting end 202. The lifting member 23 is arranged in the mounting cavity 211, and the lifting member 23 is drivingly connected to the sleeve 22, and the lifting member 23 is used to drive the sleeve 22 to rise and fall relative to the column 21.

[0050] In this embodiment, the column 21 is connected to the base 10 through the connection end 201 formed at the bottom thereof, which can ensure a stable connection between the support 20 and the base 10. Among them, the column 21 is provided with an installation cavity 211 and an opening 212. The installation cavity 211 is used to accommodate the lifting member 23. The opening 212 at the top of the column 21 is connected to the installation cavity 211, providing space for the lifting of the sleeve 22. The sleeve 22 is slidably mounted on the column 21, and the end thereof away from the column 21 forms a lifting end 202, which is connected to the connecting beam 30, so as to realize the lifting and installation of the chute 01. Specifically, the inner diameter of the sleeve 22 is larger than the outer diameter of the column 21, ensuring that it can be smoothly lifted and lowered along the column 21. The lifting member 23 is arranged in the installation cavity 211 of the column 21 and is drivingly connected to the sleeve 22. The main function of the lifting member 23 is to drive the sleeve 22 to lift and lower relative to the column 21, thereby adjusting the overall height of the device.

[0051] like Figure 5 As shown, the adjustment assembly 40 includes a screw rod 41, a nut 42 and a lifting drive 43. The screw rod 41 is fixed to the lifting end 202, extends in the vertical direction and is located on one side of the pillar 20. The nut 42 is threadedly connected to the screw rod 41, and the nut 42 is rotatably arranged on the connecting beam 30. The lifting drive 43 is arranged on the connecting beam 30, and the lifting drive 43 is drivingly connected to the nut 42, and the lifting drive 43 can drive the nut 42 to rotate, so as to drive the connecting beam 30 to rise and fall relative to the pillar 20.

[0052] In this embodiment, the screw rod 41 is fixedly connected to the lifting end 202 and extends in the vertical direction to one side of the pillar 20, and the length of the screw rod 41 should be the same as the depth of the sleeve 22 to avoid interference between the screw rod 41 and the base 10 when the sleeve 22 is lowered to the lowest position. At the same time, the setting position of the screw rod 41 needs to consider the balance and stability of the structure to avoid unnecessary shaking during the lifting process. The nut 42 is threadedly connected to the screw rod 41, and the nut 42 is freely rotatably arranged on the connecting beam 30. The above method can ensure that when the nut 42 is driven to rotate, it can move up and down along the screw rod 41, thereby driving the lifting of the connecting beam 30. The lifting drive 43 is arranged on the connecting beam 30 and is connected to the nut 42, and can drive the nut 42 to rotate. When the lifting drive 43 is started, it transmits the rotational torque to the nut 42, so that the nut 42 rotates along the direction of the screw rod 41, thereby realizing the lifting and lowering adjustment of the connecting beam 30 relative to the screw rod 41.

[0053] Further, the adjustment assembly 40 also includes a driving wheel 431, a driven wheel 432 and a worm 433. The driving wheel 431 is rotatably arranged on the connecting beam 30, and the lifting drive member 43 is drivingly connected to the driving wheel 431. The driven wheel 432 is meshed with the driving wheel 431, and the worm 433 rotates synchronously with the driven wheel 432. The outer wall of the nut 42 is provided with a toothed structure 421, and the worm 433 is meshed with the toothed structure 421. In this embodiment, the driving wheel 431 is freely rotatably installed on the connecting beam 30, and the driving wheel 431 is directly connected to the output shaft of the lifting drive member 43. When the lifting drive member 43 is started, the driving wheel 431 rotates accordingly. The driven wheel 432 is meshed with the driving wheel 431 through gears to form a gear transmission system. When the driving wheel 431 rotates, the driven wheel 432 also rotates synchronously, thereby transmitting the rotational motion of the driving wheel 431 to the subsequent transmission components. The worm 433 rotates synchronously with the driven wheel 432, and its design purpose is to convert the rotational motion of the driven wheel 432 into linear motion. One end of the worm 433 is fixedly connected to the driven wheel 432, and the other end is meshed with the toothed structure 421 provided on the nut 42. The outer wall of the nut 42 is provided with a toothed structure 421 matching the worm 433. When the worm 433 rotates, the nut 42 moves along the axial direction of the screw 41.

[0054] Furthermore, the connecting beam 30 includes a pivot sleeve 31 and a beam body 32. The pivot sleeve 31 is sleeved on the lifting end 202, and a hydraulic clamping piece 311 is provided between the inner wall of the pivot sleeve 31 and the outer wall of the lifting end 202, and the hydraulic clamping piece 311 locks or unlocks the position between the pivot sleeve 31 and the lifting end 202. One end of the beam body 32 is connected to the pivot sleeve 31, and the other end of the beam body 32 is connected to the grab assembly 50. In this embodiment, the connecting beam 30 mainly includes two major parts: the pivot sleeve 31 and the beam body 32. The pivot sleeve 31 is sleeved on the lifting end 202, and plays the role of connecting the pillar 20 and the beam body 32. A hydraulic clamping piece 311 is provided between the inner wall of the pivot sleeve 31 and the outer wall of the lifting end 202. The hydraulic clamping piece 311 can be pressed against the outer wall of the lifting end 202 by the pressure of the hydraulic oil, thereby forming a clamping state to ensure that the relative position between the pivot sleeve 31 and the lifting end 202 is fixed. When the hoisting height or angle needs to be adjusted, the oil pressure of the hydraulic clamping piece 311 is controlled to make it break away from the contact with the outer wall of the lifting end 202, unlock the position lock between the pivot sleeve 31 and the lifting end 202, and realize the free rotation or movement of the pivot sleeve 31. The beam body 32 is the main part of the connecting beam 30, one end of which is fixedly connected to the pivot sleeve 31, and the other end is connected to the grab assembly 50.

[0055] Specifically, the beam body 32 includes a connecting section 321 and a bending section 322. The connecting section 321 is fixedly connected to the pivot sleeve 31, one end of the bending section 322 is hinged to the connecting section 321, and the other end is rotatably connected to the grab assembly 50, so that the position of the grab assembly 50 can be changed, thereby improving the flexibility and practicality of the grab assembly 50.

[0056] like Figures 6 to 8 As shown, the grab assembly 50 includes a base 51, a clamping drive 52 and a clamping assembly 53. The base 51 is arranged at one end of the connecting beam 30 away from the pillar 20. The clamping drive 52 is arranged on the base 51. The clamping assembly 53 has a clamping claw 531, and the clamping drive 52 is driven and connected with the clamping claw 531 to clamp the chute to be installed. In this embodiment, the base 51 is used to support and fix the clamping drive 52 and the clamping assembly 53. The base 51 is installed at one end of the connecting beam 30 away from the pillar 20, which can ensure that when the grab assembly 50 is working, the center of gravity of the chute 01 can stably fall within the range of the grab assembly 50, thereby avoiding the shaking or imbalance of the chute 01 during the lifting process. The clamping drive 52 can be a hydraulic cylinder, an electric cylinder, etc., which provides power to the clamping claw 531 of the clamping assembly 53, so that the clamping claw 531 can accurately and forcefully clamp the chute 01. The clamping assembly 53 includes clamping jaws 531, which clamp from both sides of the chute 01. The clamping jaws 531 are connected to the clamping drive 52 through mechanical transmission to ensure that the clamping force can be evenly and reliably transmitted to the contact point of the chute 01.

[0057] Furthermore, the clamping assembly 53 includes two clamping jaws 531, which are movably arranged on the base 51. The clamping assembly 53 also includes a connecting rod 532 and a rocker rod 533. The middle part of the connecting rod 532 is connected to the clamping drive member 52, and the connecting rod 532 is movably arranged on the base 51. The two ends of the connecting rod 532 are respectively provided with rocker rods 533, one end of the rocker rod 533 is hinged to the connecting rod 532, and the other end of the rocker rod 533 is hinged to the clamping jaws 531. The clamping drive member 52 cooperates with the connecting rod 532 and the rocker rod 533 to drive the two clamping jaws 531 to move closer to or away from each other.

[0058] In this embodiment, the clamping jaws 531 are designed to have a shape that fits the surface of the chute 01, so as to provide sufficient contact area and gripping force when grasping. The clamping jaws 531 are connected to the swing rod 533 through the sliding block 534, so that when the swing rod 533 moves, the clamping jaws 531 can move accordingly to achieve the function of clamping or releasing the chute 01. The connecting rod 532 is a long strip-shaped component, the middle of which is connected to the clamping drive member 52 through a hinge point, and a swing rod 533 is connected to each of the two ends of the connecting rod 532. The above structure can evenly transmit the force of the clamping drive member 52 to the two swing rods 533, thereby ensuring the synchronization of the movement of the two clamping jaws 531 and the balanced clamping of the chute 01. One end of the swing rod 533 is hinged to the connecting rod 532, and the other end is hinged to the sliding block 534. When the clamping drive member 52 pushes the connecting rod 532, the two ends of the connecting rod 532 will drive the swing rod 533 to rotate around the hinge point. The swing of the swing rod 533 is converted into the lateral movement of the sliding block 534 , that is, the two clamping claws 531 will move closer to or away from each other, thereby clamping or releasing the chute 01 .

[0066] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0067] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
