DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-7 , the present invention provides a technical solution:

[0024] In order to realize the flexible clamping function of the device, a mine construction support frame is proposed, including a machine body 1, a front and rear clamping plate adjustment mechanism 2, and a side clamping plate adjustment mechanism 3. Four support legs 101 are arranged at the four corners of the lower end of the machine body 1. The support legs 101 can adjust their own heights through screws. The front and rear clamping plate adjustment mechanism 2 is arranged in the machine body 1. The first clamping plate 207 in the front and rear clamping plate adjustment mechanism 2 is located outside the machine body 1. The front and rear faces of the machine are clamped by the first clamping plate 207. The gear 203 in the front and rear clamping plate adjustment mechanism 2 is meshed with the second rack 301 in the side clamping plate adjustment mechanism 3. The second rack 301 drives the second clamping plate 316 in the side clamping plate adjustment mechanism 3 to move, thereby clamping the side of the machine.

[0025] The front and rear clamping plate adjustment mechanism 2 includes: an electric extension rod 201, a gear 203, and a first clamping plate 207. The fixed rod end of the electric extension rod 201 is fixedly arranged in the machine body 1. The movable rod end of the electric extension rod 201 is fixedly connected to the first rack 202. The electric extension rod 201 adopts the existing technology. The first rack 202 is meshed and connected with the gear 203. The gear 203 is rotatably installed in the machine body 1. The center of the two sides of the gear 203 is fixedly connected to one end of a first screw 204. The threads of the two first screws 204 are opposite. The other end of the first screw 204 is rotatably connected to the machine body 1. 4 is threadedly connected to the first nut 205, and one end of the first connecting rod 206 is fixedly connected to the first nut 205. The first connecting rod 206 is "L"-shaped, and the other end of the first connecting rod 206 extends out of the body 1 and is fixedly connected to the first clamping plate 207. The first clamping plate 207 is located outside the body 1, and the inner surface of the first clamping plate 207 is fixedly connected to one end of the first spring 208, and the other end of the first spring 208 is fixedly connected to the body 1. The first spring 208 is sleeved on the surface of the first telescopic rod 209, and one end of the first telescopic rod 209 is fixedly connected to the first clamping plate 207, and the other end is fixedly connected to the body 1.

[0026] The extension of the electric extension rod 201 drives the first rack 202 to move, and the first rack 202 is meshed with the gear 203, and the gear 203 rotates accordingly, and the two first screws 204 fixedly connected to the gear 203 rotate accordingly. The threads of the two first screws 204 are opposite, so the first nuts 205 threadedly connected thereto move in opposite directions, and both move in the direction away from the gear 203. The movement of the first nut 205 drives the first connecting rod 206 to move, and the movement direction of the first connecting rod 206 is the same as the movement direction of the first nut 205. The first clamping plate 207 moves with the movement of the first connecting rod 206. The movement of the first clamping plate 207 pulls the first spring 208 and the first telescopic rod 209 to extend. When the first clamping plate 207 clamps the front and back of the machine, the reset elastic force of the first spring 208 will act between the first clamping plate 207 and the machine, so that the first clamping plate 207 clamps the machine equipment.

[0027] In order to achieve the clamping of the side of the machine, a mining construction support frame is proposed, in which the side clamping plate adjustment mechanism 3 includes: a second rack 301, a clamping block 303, and a second clamping plate 316. The second rack 301 is meshed and connected with the gear 203, and the second rack 301 is slidably installed in the slide rail 302. The slide rail 302 is slidably installed in the slide groove in the machine body 1. A notch is set above the slide rail 302. The upper end of the second rack 301 is fixedly connected to one end of the second push rod 310, and the other end of the second push rod 310 passes through the notch above the slide rail 302 and is in contact with the lower end surface of the push block 311. A slide groove is set on the lower end surface of the push block 311, and the other end of the second push rod 310 is slidably installed in the slide groove. Limit blocks 313 are set on both sides of the slide groove. The second push rod 310 and the push block 311 are hinged on both sides of the contact end of the second push rod 310 and the push block 311. One end of the The other end of the second connecting rod 312 is hinged to the lower end of the pushing block 311, the pushing block 311 is trapezoidal, the pushing block 311 is in contact with one side of the pushing plate 314, the pushing plate 314 is divided into two pieces, each pushing plate 314 is slidably installed in the pushing plate slide rail 3141, the pushing plate slide rail 3141 is fixedly arranged in the body 1, the other side of the pushing plate 314 is fixedly connected to one end of the third pushing rod 315, the other end of the third pushing rod 315 is fixedly connected to the second clamping plate 316, the second clamping plate 316 is arranged outside the body 1, one side of the second clamping plate 316 is fixedly connected to one end of the second spring 317, the other end of the second spring 317 is fixedly connected to the body 1, the second spring 317 is sleeved on the surface of the second telescopic rod 318, one end of the second telescopic rod 318 is fixedly connected to the second clamping plate 316, and the other end is fixedly connected to the body 1.

[0028] The rotation of gear 203 drives the second rack 301 to move in the slide rail 302. The second rack 301 moves upward and drives the second push rod 310 to move upward. The second push rod 310 applies a thrust to the push block 311, so that the push block 311 also moves upward. The push block 311 is trapezoidal and is in contact with the push plate 314. When the push block 311 continues to move upward, the push block 311 applies a thrust to the surface of the push plate 314 to make the push plate 314 move away from the push block 311 on the push plate slide rail 3141. The push plate 314 is fixedly connected to the second clamping plate 316, so the second clamping plate 316 moves in the same direction as the push plate 314. The movement of the second clamping plate 316 stretches the second spring 317 and the second telescopic rod 318. The restoring elastic force generated by the stretching of the second spring 317 acts between the second clamping plate 316 and the side of the machine, so that the second clamping plate 316 clamps the machine equipment.

[0029] If the two second clamping plates 316 of the device have reached the width of the machine, but the two first clamping plates 207 have not reached the front and rear length of the machine, the following device can be used to make the first clamping plates 207 continue to move, while the second clamping plates 316 stop moving. A notch is set on the side of the slide rail 302, and a clamping block slide rail 305 is fixed at the position of the notch. A clamping block 303 is slidably installed in the clamping block slide rail 305. The size of the clamping block 303 is the same as the size of the notch. One end of the movable rod 304 is hinged on the clamping block 303, and the other end of the movable rod 304 is hinged on the second nut 306. The second nut 306 is threadedly connected with the second screw rod 307, one end of the second screw rod 307 extends into the body 1, and the other end is located outside the body 1, the second screw rod 307 is hollow inside, the second screw rod 307 is sleeved on the outer surface of the displacement rod 308, one end of the displacement rod 308 extends into the body 1, and the other end of the displacement rod 308 is located outside the body 1, and the end of the displacement rod 308 extending into the body 1 is fixedly connected to one end of the first push rod 309, and the other end of the first push rod 309 is fixedly connected to the middle surface of the slide rail 302, and the first push rod 309 pushes the slide rail 302 to slide in the slide groove;

[0030] The length of the slide rail 302 in the device is 1.8 times the length of the second rack 301 , so when the upper end of the second rack 301 presses against the upper end of the slide rail 302 , the lower end of the second rack 301 still moves below the middle of the slide rail 302 .

[0031] A limit ring 3081 is provided on the surface of the displacement rod 308, and the limit ring 3081 can limit the maximum moving distance of the displacement rod 308. A plurality of notches are provided on one end of the displacement rod 308 outside the body 1, and detachable connecting pins are provided in the notches.

[0032] When the two second clamping plates 316 of the device have reached the width of the machine, but the two first clamping plates 207 have not reached the front and rear length of the machine, the buckle 3071 is pressed to allow the second screw rod 307 to be rotated manually. By rotating the second screw rod 307 clockwise, the second nut 306 threadedly connected thereto moves away from the slide rail 302. Since the length of the movable rod 304 remains unchanged, the movable rod 304 pulls the clamping block 303 to slide on the clamping block slide rail 305 and gradually moves toward the second rack 301 until the second rack 301 is clamped so that the second rack 301 does not move freely. The buckle 3071 is released so that the second screw rod 307 does not rotate, thereby the second nut 306 can be rotated. 06 does not rotate freely, and then the displacement rod 308 is pushed. The displacement rod 308 is fixedly connected to the slide rail 302. The displacement rod 308 is pushed to make the slide rail 302 slide in the slide groove, thereby making the second rack 301 move away from the gear 203. At this time, since the second rack 301 is fixedly connected to the second push rod 310, the second push rod 310 slides in the slide groove on the lower end face of the push block 311. Due to the action of the limit block 313, the second push rod 310 will not separate from the push block 311, thereby achieving that the rotation of the gear 203 will not drive the second rack 301 to move. When the second splint 316 no longer moves, the pin is inserted into the notch on the displacement rod 308 to fix the position of the displacement rod 308.

[0033] Working principle:

[0034] Measure the length and width data of the mechanical equipment to be placed, turn on the switch of the electric extension rod 201, and extend the electric extension rod 201. The extension of the electric extension rod 201 drives the first rack 202 to move, and the first rack 202 is meshed and connected with the gear 203. The gear 203 rotates accordingly, and the two first screws 204 fixedly connected to the gear 203 rotate accordingly. The threads of the two first screws 204 are opposite, so the first nuts 205 threadedly connected thereto move in opposite directions, and both move away from the gear 203. The first nuts 20 The movement drives the first connecting rod 206 to move, and the movement direction of the first connecting rod 206 is the same as that of the first nut 205. The first clamping plate 207 moves with the movement of the first connecting rod 206 until it reaches the length of the placed mechanical equipment. The movement of the first clamping plate 207 pulls the first spring 208 and the first telescopic rod 209 to extend. When the first clamping plate 207 clamps the front and rear of the machine, the return elastic force of the first spring 208 acts between the first clamping plate 207 and the machine, so that the first clamping plate 207 clamps the machine equipment.

[0035] When the gear 203 rotates and drives the first screw rod 204 to rotate, the gear 203 also drives the second rack 301 to move in the slide rail 302. The second rack 301 moves upward and drives the second push rod 310 to move upward. The second push rod 310 applies a thrust to the push block 311, so that the push block 311 also moves upward. The push block 311 is trapezoidal and is in contact with the push plate 314. When the push block 311 continues to move upward, the push block 311 applies a thrust to the surface of the push plate 314 to make it move upward. The pushing plate 314 moves on the pushing plate slide rail 3141 in the direction away from the pushing block 311. The pushing plate 314 is fixedly connected to the second clamping plate 316, so the second clamping plate 316 moves in the same direction as the pushing plate 314 until it reaches the width of the placed mechanical equipment. The movement of the second clamping plate 316 causes the second spring 317 and the second telescopic rod 318 to extend. The restoring elastic force generated by the extension of the second spring 317 will act between the second clamping plate 316 and the side of the machine, causing the second clamping plate 316 to clamp the machine equipment.

[0036] When the two second clamping plates 316 of the device have reached the width of the machine, but the two first clamping plates 207 have not reached the front and rear length of the machine, the buckle 3071 is pressed down so that the second screw rod 307 can be rotated manually. By rotating the second screw rod 307 clockwise, the clamping block 303 clamps the second rack 301 so that the second rack 301 does not move freely. The buckle 3071 is released so that the second screw rod 307 does not rotate, thereby preventing the second nut 306 from rotating freely. Then, the displacement rod 308 is pushed, and the displacement rod 308 is fixedly connected to the slide rail 302. The displacement rod 308 is pushed to make the slide rail 302 slide in the slide groove, thereby making the second rack 301 away from the gear 203. At this time, since the second rack 301 is fixedly connected to the second push rod 310, the second push rod 310 slides in the slide groove of the lower end surface of the push block 311. When the second clamping plate 316 does not move any more, the latch is inserted into the notch on the displacement rod 308 to fix the position of the displacement rod 308. At this time, the first clamping plate 207 continues to move, but the second clamping plate 316 does not move any more.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
