Description

Technical Field

[0001] The present application relates to the technical field of geological survey equipment, and in particular to a lifting platform for geological survey. Background Art

[0002] Geological exploration is a survey and research activity that uses various means and methods to survey and detect geology, determine the appropriate bearing layer, determine the foundation type based on the bearing capacity of the bearing layer, and calculate the foundation parameters; the lifting platform is one of the important equipment needed in the geological survey process, which is used to transport people or heavy objects in the vertical direction;

[0003] For example, a low closed height lifting platform with patent number (CN201320353409.2) includes a desktop and a bottom frame, and is characterized in that: an inner scissor fork arm and an outer scissor fork arm are arranged between the desktop and the bottom frame, the middle of the inner scissor fork arm and the outer scissor fork arm are hinged by an axis core, the lower end of the inner scissor fork arm is hinged to the left side of the bottom frame, and the lower end of the outer scissor fork arm is provided with a roller, and the roller can roll left and right on the bottom frame, and a wrench crossbeam is welded to the middle or upper part of the inner scissor fork arm, and a wrench is welded on the wrench crossbeam; a support beam is welded to the bottom or lower part of the outer scissor fork arm, and the support beam and the wrench are respectively hinged to the piston rod and cylinder barrel or cylinder bottom at the upper and lower ends of the oil cylinder; a roller is arranged at the upper end of the inner scissor fork arm, and the roller can roll on the guide rail at the bottom of the desktop; the upper end of the outer scissor fork arm is hinged to the left side of the desktop.

[0004] In the above structure, the lifting and lowering of the table top is achieved by controlling the relative positions of the hinges of the inner scissor arm and the outer scissor arm; the bottom frame is placed on the ground, and because the environment during geological survey is generally poor, it is often located on uneven ground such as mountains, fields, and wilderness; the bottom frame cannot be placed stably on the ground; generally, supporting legs are provided under the bottom frame to prevent complex ground conditions; on some grounds with relatively soft soil, when a person or a heavy object is placed on the table top, the supporting legs will squeeze the ground causing the ground under part of the supporting legs to sag, thereby making the table top unstable and causing a safety hazard.

[0005] Therefore, it is necessary to design a lifting platform for geological survey that can quickly adjust the height of multiple supporting legs to adjust the equipment to a horizontal state, and the supporting legs can contact the ground to press the soft soil downward to prevent the ground from quickly sinking after people or objects are placed on the table, causing safety hazards.

[0063] The lifting platform for geological survey also includes: a support leg 2, a squeeze plate 201, a push plate 202, a first elastic member 203, a driving member 204, and a limit assembly;

[0064] Specifically, four limiting members 205 are fixedly installed at positions near the four corners of the bottom surface of the bottom plate 1, and the bottom surface portion of the limiting member 205 is concave to form a first limiting groove 206, and the extension direction of the first limiting groove 206 is perpendicular to the bottom surface of the bottom plate 1, and the support leg 2 is movably arranged in the first limiting groove 206; a supporting foot 212 is fixedly installed on the bottom surface of the support leg 2 to increase the contact area between the support leg 2 and the ground; the side wall portion of the limiting member 205 is concave and penetrates to form a second limiting groove 207, and the second limiting groove 207 extends along the length direction of the bottom plate 1, and the extrusion plate 201 is movably arranged in the second limiting groove 207;

[0065] A driving surface 208 is formed on the extrusion plate 201, and a portion of the driving surface 208 is concave to form a convex moving groove 213. A portion of the top surface of the support leg 2 protrudes to form a connecting portion 209, and the connecting portion 209 is movably arranged in the moving groove 213; more specifically, a portion of the top surface of the connecting portion 209 is concave to form an anti-wear groove 210, and a plurality of balls 211 are arranged in the anti-wear groove 210;

[0066] Since the extrusion plate 201 and the support leg 2 are movably connected, the support leg 2 can be driven to move along the first limit groove 206 by driving the extrusion plate 201 to move along the second limit groove 207, thereby controlling the height of the support leg 2; the setting of the ball 211 can reduce the friction between the support leg 2 and the extrusion plate 201.

[0067] The first elastic member 203 is fixedly connected to the mutually adjacent surfaces of the two extrusion plates 201 which are arranged opposite to each other in the length direction; the two push plates 202 which are arranged opposite to each other are movably arranged at a position near the middle of the lower part of the bottom plate 1; the ends of the two first elastic members 203 on the left which are away from the extrusion plate 201 are fixedly connected to the push plate 202 on the left, and the ends of the two first elastic members 203 on the right which are away from the extrusion plate 201 are fixedly connected to the push plate 202 on the right, and the first elastic member 203 is a spring; four driving members 204 are installed between the two push plates 202 on the bottom plate 1, and the driving member 204 is a hydraulic cylinder, wherein the piston rods of two hydraulic cylinders are fixedly connected to the push plate 202 on the left, and the piston rods of the other two hydraulic cylinders are fixedly connected to the push plate 202 on the right, so as to squeeze the corresponding first elastic members 203;

[0068] After the hydraulic cylinder squeezes the push plate 202, the first elastic member 203 can always give the squeezing plate 201 a thrust to move along the first limiting groove 206 after being squeezed. The thrust can drive the squeezing plate 201 to move and thereby drive the supporting leg 2 to move. The arrangement of the driving member 204 and the first elastic member 203 can simultaneously drive the four supporting legs 2 to move by retracting the driving member 204, thereby adjusting multiple supporting legs 2 to contact the ground at the same time, which is convenient and quick. The supporting leg 2 can contact the ground during the movement and press the ground under the supporting leg.

[0069] The setting of the limiting component 3 can limit the extrusion plate 201 in the moving direction to fix the position of the extrusion plate 201, thereby fixing the height of the supporting leg 2;

[0070] The limiting assembly 3 includes a limiting plate 301 fixedly arranged on the extrusion plate 201 and a plug plate 302 movably arranged on the bottom plate 1, wherein a plurality of first limiting holes 303 are formed in a linear array on the limiting plate 301, and the plug plate 302 can extend into and out of the first limiting holes 303 when it moves; a moving shell 304 is also fixedly arranged on the plug plate 302, and a clamping block 305 is movably arranged in the moving shell 304, and the clamping block 305 is fixedly connected to the moving shell 304 through a second elastic member 306, and the second elastic member 306 is a spring; a clamping plate 307 is fixedly installed on the bottom plate 1, and two second limiting holes 308 are formed on the clamping plate 307, and the clamping block 305 can extend into and out of the second limiting holes 308 when it moves; an unlocking groove 309 is formed on the moving shell 304, and an unlocking block 310 is inserted through the unlocking groove 309 and fixedly connected to the clamping block 305;

[0071] Pushing the unlocking block 310 in the direction away from the second limiting hole 308 can drive the card block 305 to move out of the second limiting hole 308. At this time, moving the plug plate 302 can push the card block 305 to the position corresponding to the two second limiting holes 308. When the position of the card block 305 corresponds to the position of the second limiting hole 308 above, the plug plate 302 moves out of the first limiting hole 303 to release the limitation on the extrusion plate 201. When the card block 305 moves to the position corresponding to the second limiting hole 308 below, the plug plate 302 moves into the first limiting hole 303 to limit the extrusion plate 201.

[0072] During operation, first move the lifting platform to a suitable position, keep at least one supporting leg 2 in contact with the ground, and support the load-bearing platform 102 to a horizontal level; start the driving member 204 to push the push plate 202 to a suitable position, and the extrusion plate 201 can move under the extrusion of the first elastic member 203 until the supporting leg 2 contacts the ground, thereby adjusting the load-bearing platform 102 to a horizontal level; during the movement of the supporting leg 2, the supporting leg 2 can contact the ground under the supporting leg 2, and the soft ground can be pressed tightly under the action of the first elastic member 203 to prevent safety hazards caused by the rapid collapse of the ground after people or objects are placed on the load-bearing platform 102.
