[0026] Example

[0027] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides a mechanical repair work stand for repairing chemical fluid conveying equipment, including: a frame unit 100 and a height adjustment unit 200.

[0028] The frame unit 100 includes a walking seat 101 and a foot pedal 102 located at one end above the walking seat 101. A counterweight 103 is slidably connected to one end of the upper side wall of the walking seat 101 away from the tooth column 201. The counterweight 103 is slidably connected to the walking seat 101 through multiple groups of evenly distributed sliders and slide grooves. By setting a movable counterweight 103, the position of the counterweight 103 from the center of the walking seat 101 can be adjusted accordingly according to the height adjustment of the foot pedal 102, thereby improving the overall stability of the machine repair work frame.

[0029] Furthermore, the height adjustment unit 200 includes two tooth columns 201 fixedly mounted on one end of the upper side wall of the walking seat 101 and a lifting sleeve 202 vertically slidably connected to the tooth columns 201. The top ends of the two tooth columns 201 are commonly fixedly connected to a top reinforcing beam 210. The top reinforcing beam 210 and the top ends of the corresponding tooth columns 201 are fastened together by fastening bolts 211. By setting the reinforcing beam 210, the two tooth columns 201 can be effectively limited from the top. The setting of the fastening bolts 211 facilitates the strengthening of the reinforcing beam. 210 is separated from the gear column 201, and a rectangular frame 203 is fixedly installed on one side of each lifting sleeve 202 near the center of the walking seat 101, and the tops of the two rectangular frames 203 are fixedly connected to the lower side walls of the footrest 102, and a reinforcing block 208 is fixedly connected between the two lifting sleeves 202, and a cushion block 209 is fixedly connected between the upper side wall of the reinforcing block 208 and the lower side wall of the footrest 102. Through the arrangement of the reinforcing block 208 and the cushion block 209, the supporting stability of the rectangular frame 203 on the footrest 102 is improved;

[0030] A dual-axis output motor 204 is fixedly installed on the lower side wall of the pedal 102, and the output shaft of the dual-axis output motor 204 is fixedly connected to a transmission rod 205, and the transmission rod 205 is inserted into the rectangular frame 203 and fixedly sleeved with a driving gear 206 meshing with the gear column 201. The driving gear 206 and the gear column 201 are both made of manganese steel, and the driving gear 206 and the gear column 201 are both provided with uniformly distributed anti-skid patterns. The driving gear 206 and the gear column 201 made of manganese steel have good wear resistance and extrusion resistance. The anti-skid pattern improves the meshing stability of the two. The lower side wall of the foot pedal 102 is fixedly installed with symmetrical fixed ears 207. Each transmission rod 205 passes through the fixed ear 207 and is rotatably connected to the fixed ear 207. The setting of the fixed ear 207 can provide stable support for the transmission rod 205, effectively solving the defect that the transmission rod 205 is prone to eccentricity or deformation after long-term use. A rectangular opening matching the driving gear 206 is provided on the lifting sleeve 202.

[0031] During use, when the maintenance height of the chemical fluid conveying equipment under maintenance changes, the dual-axis output motor 204 is started to drive the driving gear 206 to rotate. The driving gear 206 will drive the rectangular frame 203 and the lifting sleeve 202 to rise along the gear column 201 during the process of meshing with the rack 201, thereby flexibly adjusting the horizontal height of the foot pedal 102. It is only necessary to control the forward and reverse rotation of the dual-axis output motor 204, and there is no need to manually splice multiple columns, tighten bolts, etc., thereby improving the maintenance efficiency of the staff for the chemical fluid conveying equipment.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
