In this embodiment, the wheel frame 2 is an I-shaped structure, including a mounting shaft and a mounting plate arranged at both ends of the mounting shaft, the mounting shaft is rotatably installed on the mounting plate through a bearing, the travel wheel 3 is fixed on the mounting shaft, and the mounting plate is connected to the wheel frame 2.

[0020] A receiving groove 301 is provided on the side of the walking wheel 3, and a group of deceleration brake mechanisms are installed on each of the wheel frames 2. The output end of each group of the deceleration brake mechanisms is located in the corresponding receiving groove 301 of the walking wheel 3. When the output end of the deceleration brake mechanism is extended, the walking wheel 3 is squeezed and rubbed, thereby achieving deceleration and stopping of the rotation of the walking wheel 3.

[0021] A group of rope guide mechanisms are respectively provided on both sides of the pump frame 1, and one group of rope guide mechanisms corresponds to two groups of deceleration and braking mechanisms. The rope guide mechanisms include two rotating rods 4 and a guide tube 5. The upper ends of the two rotating rods 4 are rotatably mounted on the support shaft 6. The support shaft 6 is mounted on the pump frame 1. The guide tube 5 is arranged on the outside of the pump frame 1. The lower end of the rotating rod 4 is connected to the input end of the corresponding deceleration and braking mechanism through the No. 1 rope 7 to control the movement of the output end of the deceleration and braking mechanism. The middle part of the rotating rod 4 is connected to the No. 2 rope 8, and the upper ends of the two groups of No. 2 ropes 8 are connected to the No. 3 rope 9. The No. 3 rope 9 passes through the corresponding guide tube 5. The No. 3 rope 9 is used to pull the rotating rod 4 to rotate it along the support shaft 6, thereby pulling the No. 1 rope 7 to drive the deceleration and braking mechanism.

[0022] Preferably, the pump frame 1 is provided with a second pulley 23 for guiding the No. 1 pull rope 7 , and the number is four sets. The No. 1 pull rope 7 is supported and guided by the second pulley 23 .

[0023] The upper ends of the two No. 3 ropes 9 of the two groups of the rope guide mechanisms are connected to the No. 4 rope 10. The No. 4 rope 10 is the total control rope of multiple groups of deceleration and braking mechanisms. When in use, the No. 4 rope 10 is wound around the No. 2 winch or connected to the steel wire rope of the No. 2 winch.

[0024] like Figure 3~4 As shown, the deceleration brake mechanism includes a movable frame 11, a through hole is provided on the wheel frame 2 for the movable frame 11 to pass through, one end of the wheel frame 2 is extended into the accommodating groove 301 and then connected to the friction disk 12, a return spring 13 is sleeved on the movable frame 11, one end of the return spring 13 abuts on the wheel frame 2, and the other end abuts on the end of the movable frame 11, a guide pulley 14 is provided on one side of the wheel frame 2, and the No. 1 pull rope 7 is connected to the movable frame 11 after passing through the guide pulley 14.

[0025] Specifically, the movable frame 11 includes a movable rod 1101 and a connecting plate 1102 arranged at the end of the movable rod 1101, the friction disk 12 is fixed to the other end of the movable rod 1101, the reset spring 13 is abutted between the wheel frame 2 and the connecting plate 1102, and a rope threading ear plate 1103 is provided on one side of the connecting plate 1102. The No. 1 pull rope 7 is fixed on the rope threading ear plate 1103 after passing around the guide pulley 14.

[0026] Under the action of the return spring 13, the movable frame 11 makes the friction disk 12 move toward the outside of the accommodating groove 301. At this time, the friction disk 12 and the walking wheel 3 are in a separated state. At this time, the walking wheel 3 can rotate freely to realize the movement of the pump frame 1; when it is necessary to limit the rotation of the walking wheel 3, the No. 4 pull rope 10 is pulled to pull the No. 1 pull rope 7, so that the movable frame 11 moves toward the wheel frame 2, and under the action of the friction disk 12, the walking wheel 3 is decelerated and braked.

[0027] Embodiment 2: Different from Example 1, Figures 5 and 6 As shown, the pump frame 1 is installed with a docking mechanism, which includes a male head 15 and a female head 16. The male head 15 is installed on the pump frame 1. The upper end of the male head 15 is a conical structure that is narrow at the top and wide at the bottom. The lower end is provided with a fitting hole, which is fitted on the mounting rod at the top of the pump frame 1 through the fitting hole. The mounting rod is arranged horizontally so that the male head 15 can be rotated along the mounting rod to achieve angle adjustment.

[0028] The female head 16 is a cylindrical structure, and at least three support bodies 17 are rotatably installed inside and are evenly distributed with the center of the female head 16 as the center of a circle. Specifically, an installation groove is provided on the inner wall of the female head 16, and the lower end of the support body 17 is rotatably installed in the installation groove through a pin shaft. The outer side of each support body 17 is connected to the inner wall of the female head 16 through a spring 18, and the spring 18 is arranged on the upper part of the support body 17. The support body 17 is used to support the conical structure of the male head 15. When in specific use, a supporting protrusion is provided on the inner side of the support body 17.

[0029] The side wall of the female head 16 is provided with rope holes 1601 of the same number as the support bodies 17 , and each of the support bodies 17 is fixedly connected with a No. 5 pull rope 19 , and the end of the No. 5 pull rope 19 passes through the corresponding rope hole 1601 , and the opening angle of the support body 17 is adjusted and controlled by pulling the No. 5 pull rope 19 .

[0030] Under the action of the spring 18, the support body 17 is pushed out toward the center of the female head 16, thereby achieving restriction on the male head 15; when it is necessary to separate the male head 15 from the female head 16, the No. 5 pull rope 19 is pulled, so that the support body 17 overcomes the elastic force of the spring 18 and moves away from the male head 15, so that the support body 17 no longer restricts the male head 15, thereby achieving separation of the male head 15 from the female head 16.

[0031] Preferably, the upper ends of the plurality of No. 5 pull ropes 19 are connected to the No. 6 pull rope 21 , and the No. 6 pull rope 21 is a general control rope for the plurality of support bodies 17 , and is used to pull the No. 5 pull ropes 19 simultaneously.

[0032] A first pulley 20 is set on the outer side of the female head 16 corresponding to the rope hole 1601. The number of the first pulley 20 is the same as the rope hole 1601. The first pulley 20 is set above the rope hole 1601. The first pulley 20 is used to guide the No. 5 pull rope 19. Two groups of first pulleys 20 can also be set corresponding to each rope hole 1601. The No. 5 pull rope 19 passes through the two first pulleys 20 in turn, which increases the support point with the No. 5 pull rope 19 and saves more effort when pulling.

[0033] Preferably, a guide rope 22 is provided at the upper end of the male head 15, a rope threading hole 1602 is provided at the top of the female head 16 for allowing the guide rope 22 to pass through, and a connecting hole 1603 is provided at the top of the female head 16. The connecting hole 1603 is arranged horizontally for connecting with a lifting equipment. Specifically, the connecting hole 1603 is connected to the steel wire rope of the No. 1 winch.

[0034] Through the setting of the guide rope 22, when the pump frame 1 needs to be taken out from the bottom of the dam, the female head 16 is placed on the guide rope 22 to make the female head 16 slide down along the guide rope 22. When the female head 16 contacts the male head 15, the male head 15 pushes the support body 17 outward under the action of gravity. When the cone at the top of the male head 15 passes over the support body 17, the support body 17 moves inward under the action of the spring 18 to support the male head 15, thereby realizing the connection between the female head 16 and the male head 15, and the female head 16 is pulled upward to pull the pump frame 1 out of the bottom of the dam.

[0043] S8. After the pumping is completed, start the No. 1 capstan and the No. 2 capstan again to pull out the pump stand 1.

[0044] During steps S6 to S8, if the pump frame 1 needs to stop working on the slope or an accident occurs, the No. 1 winch and the No. 2 winch stop running at the same time, and the pump frame 1 stops lowering. Even if the wire rope of the No. 1 winch breaks due to an accident, since the No. 2 winch stops rotating and due to the influence of gravity, the No. 4 pull rope 10 is tightened, driving each No. 1 pull rope 8 to be tightened, so that the movable frame 11 approaches the walking wheel 3, and the walking wheel 3 is decelerated and braked under the action of the friction disc 12.

Install the water pump inside the pump frame (1); S2, securely install the No. 1 winch and the No. 2 winch on the uppermost embankment, and use a crane to place the pump frame (1) on the second embankment; S3. Use a crane to place the counterweight block on the designated shore, fix the counterweight block, and fix the outlet pipe to the counterweight block; S4. Connect one end of the water pipe to the outlet of the water pump, lift the other end with a crane, move it above the outlet pipe, and manually connect the water pipe to the outlet pipe; S5, connect the water pump to the cable, and sleeve the female connector (16) onto the outside of the guide rope (22), and insert the steel wire rope of the No. 1 winch into the connecting hole (1603) and connect it to the female connector (16); S6, connect the No. 4 pull rope (10) to the wire rope of the No. 2 winch; S6. Start the No. 1 capstan and the No. 2 capstan simultaneously, and manually push the pump frame (1) down the slope; S7. After the pump frame (1) moves to the dam bottom, the No. 1 capstan and the No. 2 capstan stop releasing the steel rope and start the water pump; S8. After the pumping is completed, the No. 1 capstan and the No. 2 capstan are started again to pull out the pump frame (1); During steps S6 to S8, if the pump frame (1) needs to stop operating on the slope or an accident occurs, the No. 1 winch and the No. 2 winch stop operating at the same time. At this time, the pump frame (1) stops lowering. Since the No. 2 winch stops rotating and due to the influence of gravity, the No. 4 pull rope (10) is tightened, which drives each No. 1 pull rope (8) to be tightened, so that the movable frame (11) approaches the walking wheel (3), and the walking wheel (3) is decelerated and braked under the action of the friction disk (12).
