Description

Technical Field

[0001] This invention belongs to the field of support trolley technology, and particularly relates to an automatic wire winding support trolley. Background Technology

[0002] After tunnel or slope excavation, to control the appropriate release of surrounding rock stress and deformation, increase structural safety, and facilitate construction, initial support with low stiffness, serving as part of the permanent load-bearing structure, is implemented immediately after the excavation of soft rock tunnels. Different initial support methods are determined according to different surrounding rock grades. For surrounding rock of grade III and above, anchor bolt support is generally used during the support process. Anchor bolt support is a rod-shaped component made of metal or other materials with high tensile strength. Using mechanical devices and bonding media, it is installed in the surrounding rock or other engineering structures of underground projects to form an anchor bolt support that can withstand loads and prevent deformation of the surrounding rock. Anchor bolts can be classified into full-length bonded anchor bolts, end-anchored anchor bolts, friction anchor bolts, prestressed anchor bolts, and self-drilling anchor bolts, etc. Anchor bolts can be well integrated with arch frames, steel mesh, and shotcrete to form a combined support and enhance the support effect. Currently, support trolleys are generally used for operation. Support trolleys are self-moving devices that drill anchor holes in the roof or sidewalls of underground roadways and complete part or all of the anchor installation process. However, since the entire equipment is installed inside the tunnel, the construction environment is relatively harsh. Many tunnel sections do not have power supply nearby and require long-distance external connections. After the power supply is connected, the support trolley will sometimes move forward and sometimes backward. When moving backward, someone needs to pull the power line backward to prevent the support trolley from crushing the line during the backward movement.

[0003] Therefore, it is necessary to provide a new automatic winding support trolley to solve the above-mentioned technical problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the shortcomings of the prior art by disclosing an automatic wire winding support trolley, which solves the problem in the prior art that operators need to pull the wire backward during the backward movement of the support trolley to prevent wire from being crushed.

[0005] The technical solution adopted by this invention to solve its technical problem is: an automatic cable reel support trolley, including a chassis, a traveling mechanism at the lower end of the chassis, and an anchor arm support, a driver's cab assembly, an electrical control system, a hydraulic system, a counterweight assembly, and an external power cable reel assembly at the upper end of the chassis. The counterweight assembly and the external power cable reel assembly are located at the rear of the chassis, the anchor arm support is located at the front of the chassis, the driver's cab assembly, the electrical control system, and the hydraulic system are located in the middle of the chassis, and a working platform is provided at the front end of the anchor arm support. The device includes a cable reel, a motor, and a support frame. The support frame is equipped with a cable guiding mechanism and a cable tilt detection mechanism. The cable guiding mechanism includes a first cable guiding component and a second cable guiding component. The first cable guiding component is located at the rear of the cable reel, and the second cable guiding component is located at the middle of the rear section of the chassis. The cable tilt detection mechanism is located at the rear end of the second cable guiding component and is used to detect the degree of tilt of the cable. The motor drives the cable reel to rotate, and the cable tilt detection mechanism is communicatively connected to the motor.

[0006] Preferably, the wire tilt detection mechanism includes a first guide groove and a first distance sensor. The first guide groove is located below the second wire guiding assembly, and the first distance sensor is located on a bracket at the first guide groove. The first distance sensor is communicatively connected to the motor.

[0007] Preferably, the wire tilt detection mechanism includes a second guide groove and a second distance sensor. The second guide groove is disposed between the second wire guiding assembly and the first guide groove, and the second distance sensor is disposed on a bracket at the second guide groove. The second distance sensor is communicatively connected to the motor.

[0008] Preferably, the wire tilt detection mechanism includes a first guide groove and a first pressure sensor. The first guide groove is located below the second wire guiding assembly, and the first pressure sensor is located on the bottom of the first guide groove. The first pressure sensor is communicatively connected to the motor.

[0009] Preferably, the wire tilt detection mechanism includes a second guide groove and a second pressure sensor. The second guide groove is disposed between the second wire guiding assembly and the first guide groove, and the second pressure sensor is disposed on the bottom of the second guide groove. The second pressure sensor is communicatively connected to the motor.

[0010] Preferably, the first wire guiding assembly includes a first vertical cylinder mounted on a bracket and a first horizontal cylinder mounted on a bracket. The first horizontal cylinder is located at the lower end of the first vertical cylinder. Both the first horizontal cylinder and the first vertical cylinder are located at the end of the winding drum near the second wire guiding assembly. The first vertical cylinder is located between the winding drum and the first horizontal cylinder.

[0011] Preferably, the second wire guiding assembly includes a second vertical cylinder mounted on a bracket and a second horizontal cylinder mounted on a bracket. The second horizontal cylinder is located at the lower end of the second vertical cylinder, and two second vertical cylinders are respectively located at both ends of the second horizontal cylinder. Two baffles are provided between the first guide groove and the second guide groove, and the two baffles are respectively located at both ends of the second horizontal cylinder.

[0014] Preferably, one end of the connecting plate is rotatably mounted on the second support frame, and the other end of the connecting plate is slidably mounted with a pin. The first support frame has multiple pin holes along the height direction that are adapted to the pin.

[0015] Compared with existing technologies, in this invention, the wire emerging from the reel is guided by the first and second wire guiding components to the center of the chassis, away from the tires or tracks on both sides of the chassis. This effectively prevents the wire from being run over and provides sufficient detection time for the subsequent wire tilt detection mechanism. The wire tilt detection frame then detects the tilt of the wire between the second wire guiding component and the ground. If the wire becomes increasingly vertical, a signal is sent to the motor, which drives the reel to rotate, retrieving the wire onto the reel and making it more horizontal. This allows the wire on the ground to move away from the traveling mechanism, effectively preventing it from being run over. If the wire becomes increasingly horizontal, a signal is sent to the motor, which stops operating to prevent the wire from being pulled apart or the circuit from being broken. The wire guiding mechanism and wire tilt detection mechanism of this invention work together to automatically wind or stop the wire according to its tilt as the automatic wire winding support trolley moves backward, thus preventing the wire from being run over by the traveling mechanism, reducing manual intervention, and improving work efficiency.

[0025] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent changes or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0026] Example 1

[0027] The following is in conjunction with the appendix Figure 1-3To further describe the present invention, an automatic cable reel support trolley includes a chassis 1. A traveling mechanism 2 is located at the lower end of the chassis 1. An anchor arm support 3, a driver's cab assembly 4, an electrical control system 5, a hydraulic system, a counterweight assembly 6, and an external power supply cable reel assembly 7 are located at the upper end of the chassis 1. The counterweight assembly 6 and the external power supply cable reel assembly 7 are located at the rear of the chassis 1. The anchor arm support 3 is located at the front of the chassis 1. The driver's cab assembly 4, the electrical control system 5, and the hydraulic system are located at the middle of the chassis 1. A working platform 8 is located at the front end of the anchor arm support 3. The external power supply cable reel assembly 7 includes a cable reel 71, a motor, and a support... The frame 72 is equipped with a wire guiding mechanism 73 and a wire tilt detection mechanism 74. The wire guiding mechanism 73 includes a first wire guiding component 731 and a second wire guiding component 732. The first wire guiding component 731 is located at the rear of the winding drum 71, and the second wire guiding component 732 is located at the middle of the rear section of the chassis 1. The wire tilt detection mechanism 74 is located at the rear end of the second wire guiding component 732 and is used to detect the tilt degree of the wire. A motor drives the winding drum 71 to rotate, and the wire tilt detection mechanism 74 is communicatively connected to the motor. The automatic wire winding support trolley can utilize existing support trolley equipment. The main feature of this invention is the addition of a motor, frame 72, wire guiding mechanism 73, and wire tilt detection mechanism 74 to the external power supply winding assembly 7 to achieve automatic wire winding during the rearward movement of the support trolley, reducing personnel requirements and improving work efficiency.

[0028] The wire tilt detection mechanism 74 includes a first guide groove 741 and a first distance sensor 742. The first guide groove 741 is located below the second wire guiding assembly 732, and the first distance sensor 742 is mounted on a bracket 72 at the first guide groove 741. The width of the first guide groove 741 gradually decreases from the opening to the bottom, which facilitates limiting the position of the wire. The first distance sensor 742 is communicatively connected to the motor. (See attached diagram.) Figure 6 When the wire between the second wire guide assembly 732 and the ground approaches the first guide groove 741, the walking mechanism 2 is relatively close to the wire, especially the wire that has fallen to the ground. If no measures are taken, the wire is easily crushed. When the wire is close to the bottom of the first guide groove 741, the first distance sensor 742 senses the wire and sends a signal to the motor. The motor drives the winding drum 71 to work and retract the wire onto the winding drum 71. The wire moves away from the first guide groove 741 (from a vertical state to a horizontal state), thereby preventing the walking mechanism 2 from crushing the wire.

[0029] The wire tilt detection mechanism 74 includes a second guide groove 743 and a second distance sensor 744. The second guide groove 743 is located between the second wire guiding assembly 732 and the first guide groove 741. The second distance sensor 744 is mounted on a bracket 72 at the second guide groove 743. The width of the second guide groove 743 gradually decreases from the opening to the bottom, which facilitates limiting the position of the wire. The second distance sensor 744 is communicatively connected to the motor. (See attached diagram.) Figure 7 As the wire from the second wire guide assembly 732 to the ground approaches the second guide groove 743, the wire tends to be horizontal, meaning it is pulled relatively straight. If the wire continues to be retracted into the reel 71, it is easy for it to break or for the wire joint to break. Therefore, when the wire is against the bottom of the second guide groove 743, the second distance sensor 744 senses the wire and sends a signal to the motor, causing the motor to stop working, thereby preventing the wire from breaking or the circuit from being disconnected.

[0030] Specifically, in order for the wire to pass through the wire tilt detection mechanism 74 more effectively, a first guide wheel and a second guide wheel can be rotatably mounted on the bracket 72. The grooves of the first guide wheel and the second guide wheel are the first guide groove 741 and the second guide groove 743, respectively.

[0031] The first wire guiding assembly 731 includes a first vertical cylinder 7311 mounted on a bracket 72 and a first horizontal cylinder 7312 mounted on the bracket 72. The first horizontal cylinder 7312 is located at the lower end of the first vertical cylinder 7311. Both the first horizontal cylinder 7312 and the first vertical cylinder 7311 are located at the end of the reel 71 near the second wire guiding assembly 732. The first vertical cylinder 7311 is located between the reel 71 and the first horizontal cylinder 7312. By setting the first vertical cylinder 7311 and the first horizontal cylinder 7312, it is convenient to guide the wire of the reel 71 to the second wire guiding assembly 732, and it is also convenient to guide the wire of the second wire guiding assembly 732 to the reel 71.

[0032] Specifically, the first vertical cylinder 7311 is located at one end of the first horizontal cylinder 7312, and the limiting plate is located at the other end of the first horizontal cylinder 7312.

[0033] The second wire guiding assembly 732 includes a second vertical cylinder 7321 mounted on a bracket 72 and a second horizontal cylinder 7322 mounted on the bracket 72. The second horizontal cylinder 7322 is located at the lower end of the second vertical cylinder 7321, and the two second vertical cylinders 7321 are respectively located at both ends of the second horizontal cylinder 7322. Two baffles 7323 are provided between the first guide groove 741 and the second guide groove 743. The two baffles 7323 are respectively located at both ends of the second horizontal cylinder 7322 and are part of the bracket 72. By setting the second vertical cylinder 7321, the second horizontal cylinder 7322, and the baffles 7323, the wire is guided to the middle position of the chassis 1, away from the tires or tracks on both sides of the chassis 1. This arrangement can effectively prevent the walking mechanism 2 from crushing the wire.

[0034] The first vertical cylinder 7311, the second vertical cylinder 7321, the first horizontal cylinder 7312, and the second horizontal cylinder 7322 are rotatably connected to the bracket 72. This arrangement makes it easier to guide the wires in and out.

[0035] See attached document Figure 4-5 The support frame 72 includes a first support frame 721 and a second support frame 722. The second support frame 722 is rotatably mounted on the first support frame 721, and the first support frame 721 is fixed to the chassis 1. A connecting plate 723 is provided between the first support frame 721 and the second support frame 722 to fix the second support frame 722. A first wire guide assembly 731 is mounted on the first support frame 721, and a second wire guide assembly 732 and a wire tilt detection mechanism 74 are mounted on the second support frame 722. In use, the second support frame 722 is extended backward and then fixed to the first support frame 721 by the connecting plate 723. When not in use, the second support frame 722 is rotated forward and stored above the chassis 1, thereby making more efficient use of the space of the automatic winding support trolley.

[0036] One end of the connecting plate 723 is rotatably mounted on the second support frame 722, and the other end of the connecting plate 723 is slidably mounted with a pin 724. The first support frame 721 has multiple pin holes 100 along its height direction that are adapted to the pin 724. By sliding the pin 724, the pin 724 is pulled out from the pin holes 100, and the second support frame 722 is retracted to the top of the chassis 1. Specifically, the second support frame 722 is housed at the rear end of the counterweight assembly 6. By providing multiple pin holes 100, the angle at which the second support frame 722 extends backward can be adjusted, thereby facilitating the adjustment of the position of the first guide groove 741 according to the site conditions.

[0037] Specifically, the second support frame 722 is located at the end of the first support frame 721 away from the reel 71. The first support frame 721 includes a first upright plate and a first horizontal plate fixed to the first upright plate. The first wire guide assembly 731 is mounted on the first horizontal plate, and a pin hole 100 is provided on the first upright plate. The second support frame 722 is hook-shaped and has a groove for receiving the connecting plate 723. The bracket 72 has a simple overall structure, is easy to store, and can make reasonable use of the space above the chassis 1.

[0038] Example 2

[0039] This embodiment is basically the same as Embodiment 1, except that:

[0040] The wire tilt detection mechanism 74 includes a first guide groove 741 and a first pressure sensor. The first guide groove 741 is located below the second wire guiding assembly 732, and the first pressure sensor is located on the bottom of the first guide groove 741. The width of the first guide groove 741 gradually decreases from the opening to the bottom. The first pressure sensor is communicatively connected to a motor. When the wire between the second wire guiding assembly 732 and the ground approaches the first guide groove 741, the walking mechanism 2 is relatively close to the wire, especially to the wire that has fallen to the ground. If no measures are taken, the wire is easily crushed. When the wire rests against the bottom of the first guide groove 741, the first pressure sensor senses the pressure from the wire and sends a signal to the motor. The motor drives the winding drum 71 to work, retrieving the wire onto the winding drum 71. The wire moves away from the first guide groove 741, thereby preventing the walking mechanism 2 from crushing the wire.

[0041] The wire tilt detection mechanism 74 includes a second guide groove 743 and a second pressure sensor. The second guide groove 743 is located between the second wire guiding assembly 732 and the first guide groove 741. The second pressure sensor is located on the bottom of the second guide groove 743. The width of the second guide groove 743 gradually decreases from the opening to the bottom. The second pressure sensor is communicatively connected to a motor. When the wire from the second wire guiding assembly 732 to the ground approaches the second guide groove 743, the wire tends to be horizontal, meaning it is pulled relatively straight. If the wire continues to be retracted to the reel 71, it is easy to break, or the wire joint may break. Therefore, when the wire rests against the bottom of the second guide groove 743, the second pressure sensor senses the pressure from the wire and sends a signal to the motor, causing the motor to stop working, thereby preventing the wire from breaking or the circuit from being disconnected.

[0042] In this invention, the wire emerging from the reel 71 is guided by the first wire guiding assembly 731 and the second wire guiding assembly 732 to the middle position of the chassis 1, away from the tires or tracks on both sides of the chassis 1. This effectively prevents the wire from being crushed and provides sufficient detection time for the subsequent wire tilt detection mechanism 74. The wire tilt detection frame then detects the tilt of the wire between the second wire guiding assembly 732 and the ground. If the wire becomes increasingly vertical, a signal is sent to the motor, which drives the reel 71 to rotate, retrieving the wire onto the reel 71 and making the wire more horizontal. This allows the wire on the ground to move away from the traveling mechanism 2, effectively preventing the wire from being crushed. If the wire becomes increasingly horizontal, a signal is sent to the motor, which stops working to prevent the wire from being pulled apart or the circuit from being broken. The wire guiding mechanism 73 and the wire tilt detection mechanism 74 work together to automatically wind or stop the wire according to its tilt as the automatic winding support trolley moves backward, thus preventing the wire from being crushed by the traveling mechanism 2, reducing manual intervention, and improving work efficiency.
