Detailed implementation mode

[0020] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with the specific implementation mode:

[0021] As Figure 1 , Figure 2 shown, the present utility model provides a transfer vehicle for flange forging, including a base 101 and a belt 109. Four corners of the bottom of the base 101 are fixedly connected with support legs 102. Two symmetrically arranged first fixing rods 103 are fixedly connected to the right end of the top of the base 101. A pull rod 104 is fixedly connected to the right side wall of the base 101. The top of the pull rod 104 is fixedly connected with a handle 105. A sliding fixing assembly 2 is arranged on the left side of the top of the base 101. The upper end of the right side wall of the first fixing rod 103 is fixedly connected with a drive motor 106. The output end of the drive motor 106 penetrates to the left side wall of the first fixing rod 103 and is connected with a turntable 107. The outer wall of the turntable 107 is in transmission connection with another turntable 107 at the lower end through a belt 109 arranged. Four inner support fixing assemblies 3 are arranged on the left side of the first fixing rod 103. Roller adjusting assemblies 4 are arranged on the opposite sides of the left and right groups of support legs 102.

[0022] The user can push and pull the device through the provided pull rod 104 and handle 105. The provided drive motor 106 can provide power for the inner support fixing assembly 3 to drive the arc plate 306 to move outward. At the same time, due to the arrangement of the sliding fixing assembly 2, the flange to be transferred can be moved to the outer surface of the inner support fixing assembly 3 by moving the vertical fixing rod 204, and then the sliding fixing assembly 2 is fixed. Since the roller adjusting assembly 4 is also arranged, after loading the flange, the wheels can be lowered and raised by controlling the roller adjusting assembly 4, which is convenient for the stable parking of the transfer vehicle and adapting to different concave and convex ground.

[0023] AsFigure 3 As shown in the figure, the sliding and fixing component 2 includes a groove 201 which is opened at the left end of the top of the base 101. A slider 202 with bumps on both the front and back sides is slidably connected to the inner wall of the groove 201. A support plate 203 is fixedly connected to the top of the slider 202. Threaded holes are opened at both the front and back ends of the top of the support plate 203 and are threadedly connected with bolts two 206. Two vertically fixed rods 204 which are symmetrically arranged front and back are fixedly connected to the top of the support plate 203. Threaded holes are opened at both the upper and lower ends on the front and back sides of the two vertically fixed rods 204 and are threadedly connected with bolts one 205. Cylindrical holes are opened at both the upper and lower ends on the right side of the two vertically fixed rods 204.

[0024] During use, first, the bolt two 206 needs to be rotated and adjusted to release the fixation between the bolt two 206 and the base 101. Then, by sliding the slider 202 which is slidably connected to the groove 201, the support plate 203 and the vertically fixed rods 204 fixed to the support plate 203 are driven to move leftward. When the vertically fixed rods 204 are moved to the required distance, the flange to be transported is placed on the arc plate 306. Then, the vertically fixed rods 204 are moved again so that the left end of the cylindrical rod 307 is sleeved in the reserved opening of the vertically fixed rods 204. The inner support and fixation component 3 is fixed by tightening the bolt one 205, completing the fixation of the inner support and fixation component 3 and the feeding of the flange.

[0025] As Figure 4 shown in the figure, the inner support and fixation component 3 includes a threaded rod 301. The right end of the threaded rod 301 is fixedly connected to the left side wall of the turntable 107. A threaded sleeve 302 is threadedly connected to the outer surface of the threaded rod 301. A sliding sleeve 303 which does not contact the outer wall of the threaded rod 301 is rotatably connected to the left side of the threaded sleeve 302. Four connecting rods one 304 are rotatably connected to the outer wall of the sliding sleeve 303 in an annular array. The ends of the four connecting rods one 304 far away from the sliding sleeve 303 are all rotatably connected to a rib 305. Arc plates 306 are fixedly connected to the sides of the four ribs 305 away from each other. The left end of the threaded rod 301 is rotatably connected to a cylindrical rod 307. Fixed rings one 309 are fixedly connected to both the front and back ends of the outer side wall of the cylindrical rod 307. Four connecting rods two 308 are rotatably connected to the outer wall of the fixed ring one 309 in an annular array. The ends of the connecting rods two 308 far away from the fixed ring one 309 are all rotatably connected to the side walls of the ribs 305.

[0026] After the flange is loaded, the driving motor 106 is started. The driving motor 106 drives the connected turntable 107 to rotate. The belt 109 arranged on the turntable 107 enables the two turntables 107 to rotate simultaneously. When the turntable 107 rotates, the threaded rod 301 fixedly connected thereto rotates. When the threaded rod 301 rotates, the threaded sleeve 302 threadedly connected thereto will move along the direction of the threaded rod 301. The movement of the threaded sleeve 302 drives the sliding sleeve 303 to move. At the same time, the connecting rod one 304 rotatably connected to the sliding sleeve 303 will be lifted. The left end of the threaded rod 301 is rotatably connected to a cylindrical rod 307, and two fixing rings one 309 are fixed on the cylindrical rod 307. The connecting rod two 308 is rotatably connected to the fixing ring one 309. When the connecting rod one 304 is lifted, it will drive the connecting rod two 308 to move. In this way, the connecting rod one 304 and the connecting rod two 308 will drive the convex strip 305 and the arc plate 306 connected to the convex strip 305 to expand and contract outward, so as to fix the flange to be transported and prevent collision during transportation.

[0027] As Figure 4 shown, the diameter of the threaded sleeve 302 is larger than the diameter of the sliding sleeve 303, and the connection points of the connecting rod one 304 and the connecting rod two 308 with the convex strip 305 are on the same horizontal plane.

[0028] The connection points of the connecting rod one 304 and the connecting rod two 308 with the convex strip 305 being on the same horizontal plane can prevent the arc plate 306 from tilting when it is propping inward. The sliding sleeve 303 does not contact the outer wall of the threaded rod 301, and the threaded sleeve 302 can drive the sliding sleeve 303 to move.

[0029] As Figure 5 shown, the roller adjusting assembly 4 includes an L-shaped connecting rod 401, a connecting rod three 411 and two groups of left and right hinges 410. The left side of the L-shaped connecting rod 401 is hinged to the lower right side of the right side walls of the two left support legs 102 through the two hinges 410 at the left end. Two symmetrically arranged universal wheels 406 are arranged at the bottom of the raised block at the lower left end of the L-shaped connecting rod 401. The right side of the connecting rod three 411 is hinged to the lower left side of the left side walls of the two right support legs 102 through the two hinges 410 at the right end. Limit posts 408 are fixedly connected to the middle parts of the front and rear sides of the connecting rod three 411. The right end of the bottom of the connecting rod three 411 is fixedly connected to another two symmetrically arranged universal wheels 406. The right end of the L-shaped connecting rod 401 is rotatably connected to an L-shaped hook 407. Spring fixing blocks two 403 are fixedly connected to the middle parts of the front and rear sides of the L-shaped hook 407. Springs 404 are fixedly connected to the outer surfaces of the two spring fixing blocks two 403. One end of each of the two springs 404 away from the spring fixing block two 403 is fixedly connected to a spring fixing block one 402. The two spring fixing blocks one 402 are respectively fixedly connected to the middle parts of the front and rear side walls of the L-shaped connecting rod 401.

[0030] After the flange is loaded and fixed, the wheels of the transfer vehicle can be adjusted by the roller adjustment assembly 4 to adapt to different ground surfaces. When parked, the roller adjustment assembly 4 is adjusted to make the support legs 102 contact the ground so that the transfer vehicle will not slip away easily.

[0031] When the universal wheel 406 needs to contact the ground, use the foot to apply downward pressure on the L-shaped connecting rod 401, so that the L-shaped hook 407 connected to the L-shaped connecting rod 401 moves downward, and the L-shaped hook 407 and the limiting column 408 can be snapped together under the tension of the spring 404, so that the connecting rod three 411 connected to the limiting column 408 will be fixed, so that the four universal wheels 406 can contact the ground at the same time. When the transfer vehicle needs to be parked, since the L-shaped hook 407 is connected to the L-shaped connecting rod 401, by rotating the L-shaped hook 407 clockwise, under the action of the tension of the spring 404, the L-shaped hook 407 and the limiting column 408 are untied, so that the bottom of the supporting leg 102 can contact the ground, and the transfer vehicle can be parked stably.

[0032] The following is a detailed description of the working principle of the transfer vehicle for flange forging.

[0033] like Figures 1-5 As shown, firstly, the bolt 206 needs to be rotated and adjusted to release the fixation between the bolt 206 and the base 101, and then the slider 202 slidably connected to the groove 201 is driven to move the support plate 203 and the vertical fixing rod 204 fixed to the support plate 203 to the left. When the vertical fixing rod 204 is moved to the required distance, the flange to be transferred is placed on the arc plate 306, and then the vertical fixing rod 204 is moved again so that the left end of the cylindrical rod 307 is sleeved in the reserved opening of the vertical fixing rod 204, and the inner support fixing assembly 3 is fixed by tightening the bolt 1 205, thereby completing the fixation of the inner support fixing assembly 3 and the flange loading.

[0034] After the flange is loaded, the driving motor 106 is started. The driving motor 106 drives the connected turntable 107 to rotate. The belt 109 provided on the turntable 107 enables the two turntables 107 to rotate simultaneously. When the turntable 107 rotates, the threaded rod 301 fixedly connected thereto rotates. When the threaded rod 301 rotates, the threaded sleeve 302 threadedly connected thereto will move along the direction of the threaded rod 301. The movement of the threaded sleeve 302 drives the sliding sleeve 303 to move. At the same time, the connecting rod 304 rotatably connected to the sliding sleeve 303 will be lifted. The left end of the threaded rod 301 is rotatably connected to a cylindrical rod 307, and two fixing rings 309 are fixed on the cylindrical rod 307. The connecting rod 308 is rotatably connected to the fixing ring 309. When the connecting rod 304 is lifted, it will drive the connecting rod 308 to move. In this way, the connecting rod 304 and the connecting rod 308 will drive the convex strip 305 and the arc plate 306 connected to the convex strip 305 to expand and contract outward, so as to fix the flange to be transported and prevent collision during transportation.

[0035] Finally, when the casters 406 need to contact the ground, apply downward pressure to the L-shaped connecting rod 401 with the foot, so that the L-shaped hook 407 connected to the L-shaped connecting rod 401 moves downward. Under the tension of the spring 404, the L-shaped hook 407 and the limit post 408 can be buckled together. Then the connecting rod 411 connected to the limit post 408 will be fixed, so that the four casters 406 can contact the ground simultaneously. When the transport cart needs to be parked, since the L-shaped hook 407 is rotatably connected to the L-shaped connecting rod 401, by rotating the L-shaped hook 407 clockwise, under the action of the pulling force of the spring 404, the L-shaped hook 407 is released from the limit post 408. Then the bottom of the support leg 102 can contact the ground to stably park the transport cart.

[0036] The above generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are all within the protection scope of the present invention.
