Description

Technical Field

[0001] This invention relates to the field of engineering construction machinery technology, and in particular to a rope winding system for a plate inserter, as well as the plate inserter and its installation method. Background Technology

[0002] The existing wire rope winding system of the insertion plate machine has fixed guide pulleys at the top and bottom of the frame, and a wire rope tensioning pulley in the middle of the frame. The tension of the wire rope is achieved by a hydraulic cylinder in the middle lifting the wire rope tensioning pulley, thus tensioning the closed wire rope. The wire rope drum rotates in both directions, enabling the wire rope to drive the drainage hose to insert into the ground or pull it out.

[0003] The traditional solution has the following disadvantages: (1) The cylinder diameter area of ​​the tensioning hydraulic cylinder needs to be very large, otherwise it cannot withstand the insertion force of 20 tons or more when the pipe is inserted into the ground. The wire rope on the winch drum is prone to loosening, causing the wire rope to jump out of the drum groove and thus fail to work properly. (2) If the cylinder diameter area of ​​the hydraulic cylinder is too large, it will also result in heavy weight. In addition, the guide rail of the tensioning pulley increases the pressure on the frame. The specifications and dimensions of the frame structure materials must be increased. The lifting torque of the frame when raising or lowering the frame is very large. The matching excavator model needs to be very high-configuration, resulting in high operating costs. Summary of the Invention

[0004] In order to solve at least one of the above-mentioned technical problems, the purpose of this invention application is to provide a rope winding system for a plate inserter that is ingeniously structured, highly reliable, and low-cost, as well as the plate inserter and its installation method.

[0005] The technical solution adopted by this invention to solve its technical problem is: A rope winding system for a plate inserter, comprising: frame; A wire rope tensioning mechanism is located at the lower part of the frame; A fixing mechanism, connected to the wire rope tensioning mechanism, is used to lock the tension state of the wire rope after it is tensioned. A reversing pulley block is provided at at least one end of the top or middle of the frame; The drum and the winch that drives the drum to rotate are located at the lower part of the frame; The wire rope is wound sequentially around the drum, the reversing pulley block, and the wire rope tensioning mechanism to form a closed loop.

[0006] As a further preferred embodiment of the present invention, the wire rope tensioning mechanism includes: a tensioning pulley group, a tensioning pulley, and a hydraulic cylinder; the tensioning pulley is disposed on the tensioning pulley group, the wire rope is wound around the tensioning pulley, and the hydraulic cylinder is connected to the tensioning pulley group for tensioning the wire rope.

[0007] As a further preferred embodiment of the present invention, the fixing mechanism includes a toothed plate, a chain, a locking block, an adjusting screw, and an adjusting nut. The toothed plate is fixed on the frame. One end of the chain is connected to the tensioning pulley group, and the other end of the chain is connected to the adjusting screw. The locking block is snapped onto the toothed plate. After the adjusting bolt passes through the locking block, the adjusting nut tensions the chain.

[0008] As a further preferred embodiment of the present invention, it also includes a drainage hose insertion tube, wherein the top end of the drainage hose insertion tube is provided with the wire rope traction fixing ear plate.

[0009] As a further preferred embodiment of the present invention, the wire rope includes a lower insertion wire rope and an upper pulling wire rope; One end of the lower insertion steel wire rope is fixed to the first side of the drum, and the other end of the lower insertion steel wire rope is wrapped around the drum and then passes through the reversing pulley group and the tensioning pulley in sequence before being fixed to the ear plate. One end of the upward-pulling wire rope is fixed to the second side of the drum, and the other end of the upward-pulling wire rope is wound around the drum, passes through the reversing pulley group, and is fixed to the ear plate.

[0010] As a further preferred embodiment of the present invention, the frame is also provided with avoidance rollers or avoidance pulleys to prevent the wire rope from contacting the frame members.

[0011] As a further preferred embodiment of the present invention, the drainage hose is provided with a guide shoe outside the hose.

[0012] As a further preferred embodiment of the present invention, the drum is a double drum of equal diameter and linked together, and the rope winding system is symmetrically arranged on the frame, sharing the same winch to control the double drum to realize the double rope traction of the drainage hose insertion pipe.

[0013] A plate inserter, including the aforementioned rope winding system.

[0014] A method for installing a rope winding system in a plate inserter, applicable to the rope winding system, includes the following steps: The frame on which the inserter is mounted; One end of the lower insertion steel wire rope is fixed to the first side of the drum, and the other end of the lower insertion steel wire rope is wound around the drum. After reaching the safety number of N turns, it passes through the reversing pulley group and the tensioning pulley in sequence and is fixed to the ear plate. One end of the upward-pulling steel wire rope is fixed to the second side of the drum, and the other end of the upward-pulling steel wire rope is wound around the drum to achieve the required release length and the number of safety turns N when the drainage hose is inserted. Then, it is fixed to the ear plate through the reversing pulley group; wherein, N is greater than or equal to 1. The rod of the hydraulic cylinder is activated to extend outward, thereby tensioning the wire rope of the entire enclosed rope winding system. Once the wire rope is tensioned, the adjusting nut of the fixing mechanism is tightened. When the wire rope tensioning closed loop becomes loose, the hydraulic cylinder rod is repeatedly activated to extend outward, thus tensioning the wire rope in the entire closed winding system and readjusting the adjusting nut.

[0015] The beneficial effects of this invention are as follows: The rope winding system, the inserter, and the installation method of this invention solve the problem of wire rope slackness and malfunction in the winch drum due to the use of a closed wire rope tensioning and fixing mechanism at the bottom of the frame. This is achieved by setting a closed wire rope tensioning and fixing mechanism in the lower part of the frame. When the hydraulic cylinder diameter in the wire rope tensioning mechanism is too small, this invention prevents the wire rope from jumping out of the groove and causing it to malfunction. Furthermore, by setting a fixing mechanism, the tension of the wire rope is locked after tensioning, eliminating the need for the tensioning mechanism to continuously generate tension force and reducing energy consumption. Since the hydraulic cylinder of this invention does not need to counteract the insertion force of the inserting tube, its cylinder diameter area can be reduced by more than two-thirds compared to traditionally used hydraulic cylinders. This eliminates the need for a large-diameter hydraulic cylinder, effectively reducing its own weight, frame pressure, and the lifting torque required for raising or lowering the frame. Consequently, it eliminates the need for a high-configuration excavator, reducing operating costs. Attached Figure Description

[0022] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0023] Reference Figures 1-1 to 1-5 , Figures 2-1 to 2-5 , Figures 6-1 to 6-5 A rope winding system for a plate inserter can be installed inside or outside the frame 10; it includes the frame 10 and a drainage pipe 11. A wire rope tensioning mechanism 12 is located at the lower part or bottom of the frame 10. The wire rope tensioning mechanism 12 can be designed as a wire rope tensioning box, with a tensioning pulley 21 installed inside the box that can move along an internal slide rail; and an adjustable tensioning pulley fixing mechanism 30 is provided to prevent slack in the closed-loop wire rope system, connected to the wire rope tensioning mechanism 12, for locking the tension state of the wire rope after it is tensioned. A reversing pulley group 40 is located at at least one end of the top or middle of the frame 10, for example, the reversing pulley group 40 may be located at the middle and top of the frame 10, or only at the top of the frame 10. The drum 61 and the winch 60 that drives the drum 61 to rotate, such as the wire rope tensioning box or the frame 10, are mounted on the upper part of the winch and are reversible. The winch is located at the lower part of the frame 10. The drum of the winch is a single drum or a double drum of equal diameter, linked (integrated). The wire rope forms a closed loop by sequentially winding around the drum 61, the reversing pulley block 40, and the wire rope tensioning mechanism 12.

[0024] By moving the traditional wire rope tensioning mechanism and wire rope tensioning pulley guide rail of the inserter from the middle position of the frame to the bottom or lower part of the frame, the center of gravity of the entire frame is lowered, thereby reducing the lifting torque when raising or lowering the frame, reducing the type of excavator required, and lowering the operating cost.

[0025] Reference Figure 3-5 The wire rope tensioning mechanism 12 includes a tensioning pulley block 20, a tensioning pulley 21, and a hydraulic cylinder 22. The tensioning pulley 21 is disposed within the tensioning pulley block 20. The wire rope winds around the tensioning pulley 21. The hydraulic cylinder 22 is connected to the tensioning pulley block 20 for tensioning the wire rope; for example, the hydraulic cylinder base is connected to the frame 10, and the hydraulic rod is connected to the tensioning pulley 20; or the tensioning pulley 21 is connected to the hydraulic cylinder 22.

[0026] Because the tensioning of the wire rope is carried out under no-load conditions, the hydraulic cylinder does not need to resist the insertion force of 20 tons or more when inserting the pipe into the ground. The cylinder diameter area of ​​the hydraulic cylinder can be reduced by more than two-thirds compared with the specifications used in the past, thereby reducing the lifting torque of the frame when raising or lowering it, reducing the specifications of the frame profile, and saving costs.

[0027] The wire rope tensioning mechanism 12 can be designed as a wire rope tensioning box. The wire rope tensioning box consists of a box body, a tensioning pulley block 20, an adjustable tensioning pulley fixing mechanism 30, and a hydraulic cylinder 22. The rod of the hydraulic cylinder 22 is connected to one end of the tensioning pulley block 20, and the cylinder body is anchored to the frame 10 through a connector; the other end of the tensioning pulley block 20 is connected to the chain 32 of the adjustable tensioning pulley fixing mechanism 30.

[0028] The adjustable tensioning pulley fixing mechanism 30 includes a toothed plate 31, a chain 32, a locking block 33, an adjusting screw 34, and an adjusting nut 35. The toothed plate 31 is fixed to the frame 10 or to the back of the housing. One end of the chain 32 is connected to the tensioning pulley assembly 20, and the other end is connected to the adjusting screw 34. The locking block 33 is engaged with the toothed plate 31. After the adjusting bolt 34 passes through the locking block 33, the adjusting nut 35 tensions the chain 32. The rod of the hydraulic cylinder 22 extends outward, tensioning the wire rope of the entire enclosed wire rope system. After the wire rope is tensioned, the adjusting nut 35 of the fixing mechanism 30 is adjusted to prevent the tensioning pulley 21 from retracting, thus relieving the hydraulic cylinder 22 of the load of the insertion force.

[0029] After the tensioning pulley is tensioned, an adjustable tensioning pulley fixing mechanism is provided. After the tensioning pulley on the hydraulic cylinder tensions the closed-run wire rope, the adjustable tensioning pulley fixing mechanism fixes the tensioning pulley, effectively preventing the tensioning pulley from moving under force, causing the closed-run wire rope to slack, and preventing the wire rope in the winch drum from jumping out of the groove and becoming disordered, thus preventing malfunctions such as abnormal operation.

[0030] The rope winding system of the inserting machine also includes a drainage belt insert 11, the top of which is provided with a wire rope traction fixing ear plate. For example, the top end of the drainage belt insert 11 is provided with a single-sided fixing ear plate for wire rope traction or symmetrical and equidistant two-sided fixing ear plates.

[0031] Reference Figure 8 The wire rope includes a lower insertion wire rope 50 and an upper pulling wire rope 51; for example, the wire rope winding system is such that one side of the drainage pipe 11 is connected to a wire rope to pull the pipe lower, and the other side is connected to a wire rope to pull the pipe upper.

[0032] One end of the lower insertion steel wire rope 50 is fixed to the first side of the drum 61. The other end of the lower insertion steel wire rope 50, after winding around the drum 61, passes sequentially through the reversing pulley group 40 and the tensioning pulley 21, and is fixed to the ear plate. For example, one end of the lower insertion steel wire rope 50 is fixed to one side of the drum 61, winds around the drum 61 to the reversing pulley group 40 located in the middle of the frame, winds around the pulley 180 degrees to the tensioning pulley 21, and winds around the pulley 180 degrees to the steel wire rope traction fixing ear plate at the top of the drainage hose insertion pipe 11.

[0033] One end of the upward-pulling wire rope 51 is fixed to the second side of the drum 61, and the other end of the upward-pulling wire rope 51 is wound around the drum 61, then passes through the reversing pulley group 40, and is fixed to the ear plate. For example, one end of the upward-pulling wire rope 51 is fixed to the other side of the drum 61, and after winding N turns around the drum to store the length of wire rope to be released when the insertion tube descends, the other end is anchored to the wire rope traction fixing ear plate at the top of the drainage hose insertion tube 11.

[0034] If the wire rope comes into contact with the members of the frame 10 in the wire rope channel, the frame 10 is also provided with avoidance rollers 41 or avoidance pulleys 42 to prevent the wire rope from contacting the members of the frame 10. For example, multiple avoidance rollers 41 or avoidance pulleys 42 can be provided to prevent the wire rope from contacting the members of the frame 10.

[0035] The drainage pipe 11 is provided with a pipe guide shoe 13.

[0036] Reference Figure 7 and Figure 9The drum 61 is a double drum of equal diameter and linked, with the rope winding system described in any one of claims 1-7 symmetrically arranged on the frame 10. The double drums are controlled by the same winch 60 to achieve double-rope traction of the drainage hose insertion pipe 11. For example, with a double-drum winch of equal diameter and linked (integrated) drums, a single wire rope is replaced with two wire ropes to traction the insertion pipe. The aforementioned rope winding system is symmetrically arranged at the other end of the drainage hose insertion pipe 11, achieving double-rope traction of the drainage hose insertion pipe 11. This ensures synchronous operation and symmetrical tension points for inserting the pipe core, preventing the insertion pipe from bending and deforming due to pressure caused by the tension point of a single wire rope shifting away from the insertion core. Furthermore, replacing a single wire rope with two wire ropes reduces the diameter and area of ​​the traction wire rope by 50%, which is beneficial for reducing the pulley diameter and saving costs.

[0037] A plate inserter includes the aforementioned rope winding system.

[0038] A method for installing a rope winding system in a plate inserter, using the aforementioned rope winding system, includes the following steps: The frame 10 on which the inserter is mounted; One end of the lower insertion steel wire rope 50 is fixed to the first side of the drum 61, and the other end of the lower insertion steel wire rope 50 is wound around the drum 61. After reaching the safety number of N turns, it passes through the reversing pulley group 40 and the tensioning pulley 21 in sequence and is fixed to the ear plate. One end of the upward-pulling steel wire rope 51 is fixed to the second side of the drum 61, and the other end of the upward-pulling steel wire rope 51 is wound around the drum 61 to reach the length required for release when the drainage hose insertion pipe 11 is inserted and the number of safety turns N turns is retained. Then, it is fixed to the ear plate through the reversing pulley group 40; wherein, N is greater than or equal to 1. The rod of the hydraulic cylinder 22 is activated to extend outward, thereby tensioning the wire rope of the entire enclosed rope winding system. When the wire rope is tensioned, the adjusting nut 35 of the fixing mechanism 30 is locked. When the wire rope tensioning closed-loop circuit becomes slack, the rod of the hydraulic cylinder 22 is repeatedly activated to extend outward, thus tensioning the wire rope in the entire closed winding system, and the adjusting nut 35 is readjusted. The rod of the hydraulic cylinder 22 is activated to extend outward, thus tensioning the wire rope in the entire closed wire rope system. After the wire rope is tensioned, the adjusting nut 35 of the fixing mechanism 30 is adjusted to prevent the tensioning pulley 21 from retracting, so that the hydraulic cylinder 22 does not bear the load of the insertion force.
