Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] Refer to Figure 1-6 , a detachable guide wheel, including a fixing plate 1, a bracket 2 is installed at the bottom of the fixing plate 1, a wheel body 3 is rotatably installed on the bracket 2, a guide groove is provided on the outer surface of the wheel body 3, and a guide rail 11 is engaged with the guide groove.

[0027] A pair of movable frames 4 and a pair of pneumatic push rods 6 are rotatably installed at the bottom of the fixing plate 1. A spring rod 5 is installed on a pair of movable frames 4. The top ends of a pair of spring rods 5 are connected to the output ends of a pair of pneumatic push rods 6. The bottom ends of a pair of movable frames 4 are provided with a cross plate 401. A scraper 7 is installed at the bottom of the cross plate 401. A cleaning pad 701 is provided at the bottom of the scraper 7. The cleaning pad 701 is an elastic rubber backing plate, and a flexible cotton cloth is laminated on the surface of the elastic rubber backing plate.

[0028] During the running of the guide wheel, when some debris and impurities appear on the surface of the guide rail 11, a pair of pneumatic push rods 6 are synchronously started. The output ends of the pair of pneumatic push rods 6 push a pair of spring rods 5 to move downward synchronously, causing a pair of movable frames 4 to rotate downward, driving the cross plate 401 to move downward, so that the scraper 7 at the bottom of the cross plate 401 cooperates with the guide rail 11. The cleaning pad 701 provided at the bottom of the scraper 7 is attached to and presses against the surface of the guide rail 11. A reaction force is generated by the contact between the scraper 7 and the surface of the guide rail 11. The reaction force is transmitted to the pair of movable frames 4 through the cross plate 401, causing the pair of movable frames 4 to rotate upward, thereby squeezing a pair of spring rods 5 on the pair of movable frames 4, causing the spring rods 5 to contract under force. Through the resilience of the spring rods 5, the scraper 7 and the cleaning pad 701 can be kept in a state of being attached to the surface of the guide rail 11. Larger impurities on the surface of the guide rail 11 can be scraped off by the scraper 7, and the fine debris attached to the surface of the guide rail 11 can be cleaned by the cleaning pad 701. Thus, the debris and impurities on the surface of the guide rail 11 can be conveniently and fully scraped and cleaned, effectively shortening the cleaning time, improving the working efficiency of the operating equipment, reducing the wear of the wheel body 3, increasing the service life of the wheel body 3, and ensuring that the operating equipment can walk stably.

[0029] An installation seat 8 is provided at the top of the fixed plate 1. An assembly groove 801 is opened in the middle of the top end of the installation seat 8. A connecting column 10 is fitted in the assembly groove 801. An installation plate is provided at the top end of the connecting column 10. An installation hole groove is opened in the installation plate, and the connecting column 10 can be fixed on the operating equipment. A pair of receiving grooves 802 are opened at the top end of the fixed plate 1. Through grooves 803 are opened on one side wall of each of the pair of receiving grooves 802. A locking assembly 9 is provided in each of the pair of receiving grooves 802. One end of the locking assembly 9 passes through the through groove 803 into the assembly groove 801. Slide grooves 804 are opened in each of the pair of receiving grooves 802. Sliders 9011 are provided at the bottoms of a pair of locking buckles 901. The pair of sliders 9011 cooperate with the pair of slide grooves 804. The pair of locking buckles 901 cooperate with the pair of through grooves 803. One end of the locking buckle 901 passes through the through groove 803 into the assembly groove 801. Square holes 805 are opened on the other side wall of each of the pair of receiving grooves 802. One end surface of a pair of movable rods 903 cooperates with the pair of square holes 805 and passes through the receiving groove 802 to the side of the installation seat 8. A pull ring 9031 is provided at one end of the movable rod 903.

[0030] The locking assembly 9 includes a limit plate 902 and a fixing rod 904. The limit plate 902 is in contact with the inner wall surface of the assembly groove 801 and can limit the position of the locking buckle 901. A locking buckle 901 is provided at one end of the limit plate 902. The locking buckle 901 is an arc-shaped block. A movable rod 903 is provided at the other end of the limit plate 902. Collar rings 906 are provided on both sides of the limit plate 902. There are a pair of fixing rods 904. The pair of fixing rods 904 are horizontally installed in the assembly groove 801. The surfaces of one ends of the pair of fixing rods 904 are in clearance fit with the inner rings of the pair of collar rings 906. Springs 905 are in clearance fit with the surfaces of the pair of fixing rods 904. Card slots 1001 and positioning slots 1002 are symmetrically formed on both sides of the connecting column 10 respectively. The pair of locking buckles 901 cooperate with the pair of card slots 1001, and one ends of the pair of locking buckles 901 cooperate with the pair of positioning slots 1002.

[0031] When the guide wheel needs to be replaced after long-term use, pull a pair of pull rings 9031 synchronously towards the outside of the mounting seat 8, so that the movable rod 903 slides in the square hole 805. The movable rod 903 pulls the limit plate 902 to move horizontally in the assembly groove 801, so that the locking buckle 901 slides in the through groove 803 and horizontally displaces towards the assembly groove 801. During the horizontal movement of the limit plate 902, the collar rings 906 on both sides of the limit plate 902 also move horizontally, so that a pair of collar rings 906 slide on the surface of a pair of fixed rods 904. Through the horizontal movement of the collar rings 906, one end of the collar ring 906 squeezes one end of the spring 905 fitted on the outer surface of the fixed rod 904. The spring 905 contracts under the extrusion force. Through the cooperation of the slider 9011 and the chute 804, the locking buckle 901 is separated from the card slot 1001 and slides into the assembly groove 801, thereby releasing the locking of the pair of locking components 9 on both sides of the connecting column 10. Then move the mounting seat 8 downward so that the connecting column 10 slides out of the assembly groove 801. When replacing a new guide wheel, align a pair of positioning grooves 1002 on the connecting column 10 with the front ends of a pair of locking buckles 901, and then vertically slide the connecting column 10 into the assembly groove 801, and vertically push up the mounting seat 8, so that an extrusion force is generated between the front ends of a pair of locking buckles 901 and a pair of positioning grooves 1002. The extrusion force pushes the locking buckle 901 to move towards the assembly groove 801, driving the limit plate 902 to horizontally displace, so that the collar rings 906 on both sides of the limit plate 902 squeeze the spring 905 on the surface of the fixed rod 904. The spring 905 contracts under the force. The locking buckle 901 retracts into the assembly groove 801. Continue to push up the mounting seat 8 so that a pair of locking buckles 901 slide into a pair of card slots 1001. At this time, the resilience of the spring 905 pushes the locking buckle 901 into the card slot 1001 and tightly adheres to the inner wall of the card slot 1001, so that a pair of locking buckles 901 are clamped into a pair of card slots 1001, completing the locking of the connecting column 10, thereby enabling the efficient and convenient rapid disassembly and assembly of the guide wheel, effectively shortening the disassembly and assembly time of the guide wheel, and improving the replacement rate.
