[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The height of the top cover can be adjusted by the telescopic assembly. The outer rod in the telescopic assembly is slidably inserted with the screw rod, so that the height of the screw rod can be adjusted at will. At the same time, the height of the sleeve on the surface of the screw rod can be adjusted by rotating the sleeve. When the height of the telescopic assembly needs to be adjusted, it is only necessary to rotate the sleeve to adjust its height on the surface of the screw rod. When the sleeve is overlapped on the top of the outer rod, the height of the screw rod can be adjusted. At the same time, the function of the walking wheel can facilitate the movement of the device;

[0013] 2. The base at the bottom of the installation frame can be easily disassembled and fixed by means of hooks and fixing pins with limit pins in the installation assembly. At the same time, the heat dissipation fins on the installation frame and the base can effectively dissipate the heat of the vibrating pump in the installation assembly. At the same time, the clamping plate connected by the shock-absorbing spring on the inner side of the installation frame can effectively clamp the vibrating pump while improving the stability and shock absorption capacity of the vibrating pump installation. The spring shock absorber can enhance the shock absorption capacity of the installation frame, thereby further enhancing the stability and shock absorption capacity of the high vibrating pump installation. At the same time, the moving seat on the guide column cooperates with the linear motor assembly on the straight shaft to facilitate the movement of the vibrating pump in the installation assembly;

[0014] 3. The arrangement of the winding assembly can facilitate the retraction and release of the cable. The frequency conversion motor body and the winding drum are connected through a pulley transmission with a drive belt, so that the cable after being released can be wound and reeled, which makes it convenient to rewind the cable. When releasing the cable, because the frequency conversion motor body does not have a self-locking function, it is only necessary to pull the cable to realize the rotation of the winding drum to release the cable. The end of the cable connected to the vibrating pump is connected to the fixed block, fixed pulley and guide wheel assembly in sequence. Therefore, when the linear motor assembly drives the moving seat to move back and forth on the surface of the guide column, the cable will drive the slider on the fixed pulley to slide in the limit groove. Under the action of the return spring, the slider can have a force in the direction of the original position, ensuring that the cable between the fixed block and the vibrating pump is long enough and can automatically recover.

[0025] The present invention provides Figure 1-8 A mobile tool stand for box girder concrete vibrator shown in the figure comprises a top cover 1, baffles 2 are welded on both sides of the bottom of the top cover 1, and a winding assembly 3 for installing a cable is fixedly connected to the bottom of the baffle 2, a guide column 4 is fixedly installed between two groups of baffles 2, and a moving seat 5 is slidably sleeved on both sides of the surface of the guide column 4, the bottom of the top cover 1 is located at the upper end of the guide column 4 and is fixedly installed with a straight shaft 8 through two groups of protrusions, and linear motor assemblies 9 respectively fixedly connected to the two groups of moving seats 5 are installed at both ends of the surface of the straight shaft 8, and the bottom of the moving seat 5 is fixedly installed There is a spring shock absorber 6, and the bottom of the spring shock absorber 6 is fixedly connected to an installation component 7 for installing a vibrating pump. A telescopic component 10 is also installed at the bottom corner of the top cover 1, and a walking wheel 11 is installed at the bottom of the telescopic component 10. A photovoltaic panel assembly 12 with an inverter is embedded on the top of the top cover 1, and a battery assembly 13 electrically connected to the photovoltaic panel assembly 12 through a wire is fixedly installed at the bottom front end of the top cover 1. A control switch assembly 14 electrically connected to the battery assembly 13 and the linear motor assembly 9 is also provided on one side of the top cover 1.

[0026] Specifically, the winding assembly 3 includes a mounting plate 31 fixed to the bottom of the baffle 2, and the bottom end of the outer side surface of the mounting plate 31 is respectively mounted with a variable frequency motor body 32 and a rotatable winding disk 33, the output shaft of the variable frequency motor body 32 and the rotating shaft of the winding disk 33 are both passed through the mounting plate 31 and are fixedly connected with a pulley 34, and a transmission belt is sleeved between the two sets of pulleys 34, the variable frequency motor body 32 is also electrically connected to the control switch assembly 14 through a wire, the inner side surface of the mounting plate 31 is provided with a limit groove 36, and the inner side of the limit groove 36 is slidably connected with a slider 37, and the surface of the slider 37 is fixed A fixed pulley 38 is installed, and a return spring 310 is fixedly connected between the inner end of the limit groove 36 and the slider 37. The inner side surface of the mounting plate 31 is located at the top and bottom of one end of the limit groove 36, and a guide wheel assembly 39 and a fixed block 35 are respectively installed. The guide wheel assembly 39 includes a vertical guide wheel and a horizontal guide wheel located at the top of the vertical guide wheel. One end of the cable wound on the surface of the winding drum 33 is connected to an external distribution cabinet, and the other end of the cable passes through the mounting plate 31 and is connected in sequence to the fixed block 35, the fixed pulley 38 and the guide wheel assembly 39, and then is fixedly connected to the vibrating pump in the mounting assembly 7. The frequency conversion motor body 32 and the winding drum 33 are connected through the pulley 34 with a transmission belt, so that the cable after being released can be wound and reeled, which is convenient for rewinding. When releasing the cable, because the frequency conversion motor body 32 does not have a self-locking function, it is only necessary to pull the cable to realize the rotation of the winding drum 33 to release the cable. The end of the cable connected to the vibrating pump is connected to the fixed block 35, the fixed pulley 38 and the guide wheel assembly 39 in sequence. Therefore, when the linear motor assembly 9 drives the moving seat 5 to move back and forth on the surface of the guide column 4, the cable will drive the slider 37 on the fixed pulley 38 to slide in the limit groove 36. Under the action of the return spring 310, the slider 37 can have a force in the direction of the original position, ensuring that the cable between the fixed block 35 and the vibrating pump is long enough and can automatically recover.

[0027] Specifically, a through hole with a shaft sleeve is provided at the connection between the moving seat 5 and the guide column 4, and a manually adjustable brake device is installed on the walking wheel 11. The through hole with the shaft sleeve can facilitate the linear motor assembly 9 to drive the moving seat 5 to move back and forth on the surface of the guide column 4, and the manually adjusted brake device can facilitate the fixing of the walking wheel 11, so that the walking and fixing of the tool rack can be realized.

[0028] Specifically, the mounting assembly 7 includes a mounting frame 71 fixed to the bottom of the spring shock absorber 6, and a base 72 is movably installed at the bottom of the mounting frame 71, and the front and rear ends of both sides of the base 72 are rotatably connected with hooks 73 through pin shafts, and the front and rear parts of the bottom ends of both sides of the mounting frame 71 are respectively welded with fixing pins 74 that cooperate with the hooks 73, and the outer ends of the surfaces of the fixing pins 74 are also inserted with limiting pins. The internal top end of the mounting frame 71 and the top of the base 72 are both inlaid with heat dissipation fins 75, and the top of the base 72 is also provided with through holes for the vibrating head to pass through, and shock-absorbing springs 76 are installed on both sides of the interior of the mounting frame 71, and the ends of the shock-absorbing springs 76 are fixedly connected with clamps 77 with anti-slip rubber pads. The hook 73 and the fixing pin 74 with a limit pin can facilitate the disassembly and assembly of the base 72 at the bottom of the mounting frame 71. At the same time, the heat dissipation fins 75 on the mounting frame 71 and the base 72 can effectively dissipate the heat of the vibrating pump in the mounting assembly 7. At the same time, the clamping plate 77 connected to the inner side of the mounting frame 71 by the shock-absorbing spring 76 can effectively clamp the vibrating pump while improving the stability and shock-absorbing ability of the vibrating pump installation. The spring shock absorber 6 can enhance the shock-absorbing ability of the mounting frame 71, thereby further enhancing the stability and shock-absorbing ability of the high vibration pump installation.

[0029] Specifically, the telescopic assembly 10 includes an outer rod 101 fixed on the top of the walking wheel 11, and a screw rod 102 is slidably inserted inside the outer rod 101, a sleeve 103 with an internal thread is threadedly connected to the surface of the screw rod 102, and the bottom of the sleeve 103 is integrally provided with a convex ring that fits and connects with the top of the outer rod 101, and a mounting groove corresponding to the shape and size of the screw rod 102 is provided at the connection between the top cover 1 and the screw rod 102, and an anti-collapse plate is also integrally provided at the bottom of the outer rod 101. The screw rod 102 is slidably inserted on the outer rod 101, so that the height of the screw rod 102 can be adjusted at will, and the height of the sleeve 103 on the surface of the screw rod 102 can be adjusted by rotating the sleeve 103. When the height of the telescopic assembly 10 needs to be adjusted, it is only necessary to rotate the sleeve 103 to adjust its height on the surface of the screw rod 102, so that the height of the screw rod 102 can be adjusted when the sleeve 103 is overlapped on the top of the outer rod 101, which is convenient to operate and easy to disassemble and store.

[0030] Specifically, the battery assembly 13 is equipped with an LED display screen for displaying the remaining power, and a charging interface with a waterproof sealing plug is also provided on one side of the battery assembly 13. The LED display screen can effectively display the remaining power of the battery assembly 13, and the charging interface with a waterproof sealing plug can charge the battery assembly 13 when the battery assembly 13 is low on power.

[0031] Working principle: When in use, first assemble and fix the telescopic component 10 on the bottom of the top cover 1, then rotate the hook 73 on the base 72 in the installation component 7 to disengage the fixing pin 74, install the vibrating pump between the two sets of clamping plates 77 in the installation frame 71, and at the same time reinstall the base 72 on the bottom of the installation frame 71, and then rotate the sleeve 103 in the telescopic component 10 to adjust the height of the sleeve 103 on the surface of the screw rod 102. When it is necessary to adjust the height of the telescopic component 10, it is only necessary to rotate the sleeve 103 to adjust its height on the surface of the screw rod 102, so that when the sleeve 103 is overlapped on the top of the outer rod 101, the height adjustment of the screw rod 102 can be achieved. After one end of the cable is connected to the external distribution cabinet and the other end of the cable is connected and fixed to the vibrating pump, the tool rack can be dragged to carry the vibrating pump along the box beam concrete mold for vibration operation. During the vibration operation, the control switch component 14 can be used The linear motor assembly 9 is controlled to move the movable seat 5 back and forth on the surface of the guide column 4, thereby improving the vibrating effect of the vibrating head at the bottom of the vibrating pump on the concrete. The frequency conversion motor body 32 and the winding drum 33 are connected through a pulley 34 with a transmission belt, so that the cable after the wire is released can be wound and reeled, which is convenient for wire reeling. When releasing the wire, because the frequency conversion motor body 32 does not have a self-locking function, it is only necessary to pull the cable to realize the rotation of the winding drum 33 for wire release. The end of the cable connected to the vibrating pump is connected to the fixed block 35, the fixed pulley 38 and the guide wheel assembly 39 in sequence. Therefore, when the linear motor assembly 9 drives the movable seat 5 to move back and forth on the surface of the guide column 4, the cable will drive the slider 37 on the fixed pulley 38 to slide in the limit groove 36. Under the action of the return spring 310, the slider 37 can have a force in the direction of the original position, ensuring that the cable between the fixed block 35 and the vibrating pump is long enough and can be automatically restored. The device has a simple and reasonable structural design, is easy to operate, easy to adjust, saves time and effort, improves work efficiency, is safe and stable, has a wide range of applications, and is conducive to promotion and popularization.
