Description

Technical Field

[0001] The present invention relates to the field of mud pump fixing equipment, and more particularly to a suspended mud pump. Background Art

[0002] In the construction of mud wall bored piles, a pulley is generally installed on a steel pipe tripod, and an iron chain is connected under the pulley to lift the mud pump. When the mud level is too high or too low, in order to protect the mud pump and enable it to effectively extract mud, it is often necessary to manually lift the pulley group to ensure the position of the mud pump. Using this method, not only is it necessary to manually adjust the height of the pump up and down, but also a crane is needed to replace the position of the mud pump bracket in the mud pool, which not only wastes labor, but also poses certain safety risks. Therefore, in the prior art, a variety of suspended mud pumps have been developed. When in use, the mud pump rises and falls with the rise and fall of the mud pool liquid level, which can avoid the mud pump from sucking air. For example, the patent with application number 202321614426.7 discloses a mud pump suspension fixing device, including a floating plate, a support frame and a mud pump. The floating plate has buoyancy, and a avoidance hole is opened in the middle of the floating plate; the support frame is arranged on the top surface of the floating plate, and the support frame is extended in the vertical direction. In the vertical direction, the forward projection of the support frame is located within the forward projection of the floating plate; the mud pump is arranged on the support frame, and the output end of the mud pump extends downward in the vertical direction to pass through the avoidance hole; wherein, a plurality of moving wheels are arranged at the bottom of the floating plate, and the plurality of moving wheels are evenly spaced along the outer side of the bottom of the floating plate. This mud pump suspension fixing device has a simple structure and strong integrity, and can facilitate the transfer of the device. However, in the above technical solution, when the mud pump is in use, the moving wheels are immersed in the mud throughout the whole process. When the mud pump needs to be pushed to move, the mud adhered to the moving wheels affects the moving effect of the moving wheels. If the moving wheels are cleaned, a cleaning process is added.

The driving and lifting components are arranged between the corresponding gantry 4 and the lifting plate 8. One end of the conveying and lifting component is connected to the corresponding lifting plate 8, and the other end is connected to the corresponding gantry 4. When the driving member drives the lifting plate 8 to descend from the first height to the second height, the bottom end of the mud pump 9 descends from above the bottom plate 1, passes through the through hole 11 and extends into the mud pool. At the same time, the moving wheel 13 moves upward from below the floating drum 3 through the corresponding through hole 12 to above the bottom plate 1; In the above technical solution, the bottom plate 1 is a square plate, and floating drums 3 are arranged at the bottom of the bottom plate 1 so that the bottom plate 1 can float on the mud pool surface. The floating drums 3 can be four, and the four floating drums 3 are respectively arranged at the four corners of the bottom plate 1, or the floating drums 3 can be multiple, and the multiple floating drums 3 are distributed all over the bottom of the bottom plate 1. A pair of mounting columns 19 are arranged on the bottom plate 1. The pair of mounting columns 19 are vertical and opposite to each other. Long strip holes 18 are vertically opened on the mounting columns 19, and the pair of long strip holes 18 are opposite to each other. A lifting plate 8 is slidably connected to the pair of long strip holes 18. Specifically, the lifting plate 8 is horizontally arranged. The two ends of the lifting plate 8 along its length direction are respectively located in the pair of long strip holes 18 and are slidably connected to the inner walls of the long strip holes 18 to slide along the long strip holes 18 (i.e., slide in the vertical direction). A driving member is arranged on the bottom plate 1, and the driving end of the driving member is connected to the lifting plate 8 to drive the lifting plate 8 to lift and lower; A mud pump 9 is installed on the lifting plate 8. Specifically, an installation hole is opened on the lifting plate 8, and the motor end (top end) of the mud pump 9 is detachably installed on the top of the lifting plate 8 (the inner diameter of the installation hole can be designed to be smaller than the diameter of the motor end of the mud pump 9, so that the motor end can be directly placed on the installation hole, or the motor end of the mud pump 9 can be installed on the top of the lifting plate 8 through a bracket). The bottom end (i.e., the suction end) of the mud pump 9 passes through the installation hole and extends outside the lifting plate 8. A through hole 11 is arranged in the middle of the bottom plate 1, and the through hole 11 is used for the bottom end of the mud pump 9 to pass through. It should be noted that when multiple floating drums 3 are distributed all over the bottom plate 1, a passage space for the bottom end of the mud pump 9 needs to be left between the floating drum layers (between the floating drums 3); A gantry 4 is arranged on both sides of the lifting plate 8 along its length direction. The gantry 4 is in the shape of a C-shaped rod structure. The two co-directional rod bodies of the gantry 4 are vertical, which are vertical rod bodies 401. The rod body connecting the two vertical rod bodies 401 is a horizontal rod body 402. The horizontal rod body 402 forms the top of the gantry 4. A moving wheel 13 is arranged at the bottom of the vertical rod body 401. Four through holes 12 are also arranged on the bottom plate 1, and the four through holes 12 are close to the four corners of the bottom plate 1. The four moving wheels 13 correspond to the four through holes 12 one by one; A pair of lifting plates 8 are provided with a pair of transmission lifting components on both sides along their length direction, and a pair of transmission lifting components, a pair of door frames, and a pair of lifting plates 8 have a one-to-one correspondence at their ends. The transmission lifting components are arranged between the corresponding door frames 4 and the corresponding lifting plates 8 ends. One end of the transmission lifting components is connected to the corresponding lifting plates 8, and the other end is connected to the corresponding door frame 4. Specifically, each transmission lifting component includes a first rack 5, a gear 6, and a second rack 7. The first rack 5 is vertically arranged, and the first rack 5 is located on the side of the adjacent mounting column 19 away from the other mounting column 19. The tooth ends of a pair of first racks 5 are away from each other, and the side walls of the first racks 5 away from their teeth are connected to the corresponding lifting plates 8 ends. The tooth ends of the first racks 5 are meshed with the gear 6. The gear 6 is vertically arranged, and the gear 6 is rotatably supported on the bottom plate 1. Specifically: a pair of support plates 22 are vertically arranged on the bottom plate 1, and the pair of support plates 22 correspond to a pair of gears 6, and the gear 6 is coaxially fixed with a rotating rod 2 3, the end of the rotating rod 23 away from the gear 6 is rotatably connected to the corresponding supporting plate 22; the end of the gear 6 away from the first rack 5 is meshed with the second rack 7, and the side wall of the second rack 7 away from the gear 6 is connected to the middle part of the horizontal rod body 402 of the door frame 4, so that when the driving member drives the lifting plate 8 to descend from the first height to the second height, the bottom end of the mud pump 9 descends from the top of the bottom plate 1 through the passage hole 11 and then extends into the mud pool, and at the same time, the moving wheel 13 moves upward from the bottom of the buoy 3 through the corresponding through hole 12 to the top of the bottom plate 1; in actual use, the driving member can be a driving structure such as an electric push rod or a hydraulic rod; in addition, the lengths of the first rack 5, the second rack 7, the vertical rod body 401, the mounting column 19, etc. are designed according to requirements, such as when the second rack 7 / the first rack 5 moves down to the lower end point, the bottom end of the second rack 7 / the first rack 5 is located above the top of the bottom plate 1, that is, the bottom plate 1 does not interfere with the movement of the second rack 7 / the first rack 5; In this technical solution, during use: in the initial state, the lifting plate 8 is located at a first height, at which time the bottom end of the mud pump 9 is located directly above the passage hole 11, and the moving wheel 13 is located below the buoy 3 to support the entire device on the ground. When it is necessary to pump the mud in the mud pool, the entire device is hoisted into the air, and then the driving member is started. The driving member drives the lifting plate 8 to descend to a certain height. During this process, the moving wheel 13 moves up with the descent of the lifting plate 8. When the moving wheel 13 moves up to a state close to the perforation 12 or located in the perforation 12 or located above the perforation 12, the entire device is hoisted to the mud pool, and then the driving member is continued to be started to drive the lifting plate 8. Descend until the bottom end of the mud pump 9 passes through the passage hole 11 and extends into the mud pool to a suitable depth, and at the same time, the moving wheel 13 moves up to a position above the bottom plate 1, so that the mud pump 9 can be used normally while the mud in the mud pool will not adhere to the moving wheel 13, and at this time, the lifting plate 8 is at the second height; similarly, when the suction is completed, the device is first hoisted into the air, and then the driving member is started to raise the lifting plate 8 from the first height to the second height, at this time, the bottom end of the mud pump 9 passes through the passage hole 11 and moves up to a position above the bottom plate 1, and at the same time, the moving wheel 13 passes through the corresponding through hole 12 and moves down to a position below the buoy 3, so as to form a support and facilitate the movement of the entire device; By giving the mud pump 9 the function of lifting and lowering, on the one hand, while preventing the moving wheel 13 from being affected by the mud, the depth of the mud pump 9 extending into the mud pool can be adjusted at any time. It is also suitable for mud pumps 9 of different lengths and has strong practicality. Specifically: the positional relationship between the moving wheel 13 and the bottom end of the mud pump 9 can be set as follows: when the bottom end of the mud pump 9 is close to the surface of the mud pool, the moving wheel 13 is located near the perforation 12, or is located in the perforation 12, or is located above the perforation 12. At this time, the moving wheel is no longer easily affected by the mud. At this time, the mud pump 9 can be lowered to a suitable position according to needs, so that the mud pump 9 is located in a mud pool of suitable depth. In the process of the mud pump 9 moving downward, the moving wheel 13 moves further and further away from the mud pool. , and is less susceptible to the influence of mud; at the same time, if it is necessary to apply to mud pumps 9 of different lengths, when making this device, the length information of the mud pumps 9 in the field can be collected, and the longest mud pump 9 is used as a reference, so that when the bottom end of the longest mud pump 9 is close to the liquid surface of the mud pool, the moving wheel 13 is located near the perforation 12, or is located in the perforation 12, or is located above the perforation 12. In this way, the short mud pump 9 only needs to increase the downward displacement until the bottom end of the short mud pump 9 is located in a mud pool of suitable depth, and a variety of mud pumps of different lengths can be applied; on the other hand, when the mud pump 9 is moved up to the set height, the mud pump 9 is in a space that is convenient for manual operation. At this time, the mud pump 9 can be flushed through a clean water pipe to clean the mud pump 9; The beneficial effect obtained by adopting the technical solution is that, by arranging the bottom plate 1, the buoy 3, the passage hole 11, the mounting column 19, the long strip hole 18, the perforation 12, the lifting plate 8, the mud pump 9, the first rack 5, the gear 6, the second rack 7, the door frame 4, the moving wheel 13, and the driving member, a suspended mud pump 9 is provided, and when the mud pump 9 is used, the moving wheel 13 is located above the mud pool to avoid the mud in the mud pool adhering to the moving wheel 13, which causes the movement effect to be reduced or the cleaning work to be increased. At the same time, when the mud pump 9 is not in use, the mud pump 9 is raised to a position above the bottom plate and the moving wheel 13 is extended to move the mud pump 9. After the mud pump 9 is moved up to a position above the bottom plate, the mud pump 9 is also in a position that is convenient for manual operation. At this time, the mud pump 9 can be flushed to keep the mud pump clean. In addition, since the lifting plate 8 can be raised and lowered, it can also adapt to mud pumps 9 of different lengths and models, and the depth of the mud pump 9 extending into the mud pool can also be adjusted, which greatly enhances the practicality.
