[0026] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings.

[0027] like Figure 1-Figure 4 As shown, a soil backfill elevation device includes a support component 1 that can stably install the device at a certain height outside the area to be backfilled, the support component 1 is provided with an elevation component 2 that can mark the height required for backfilling outside the area to be backfilled, and the support component 1 and the elevation component 2 are provided with an adjustment component 3 that can improve the accuracy of the elevation of the device.

[0028] In this embodiment: the support assembly 1 includes a base 101, to which an anchor rod 102 is fixedly connected, and a rotary handle 103 is fixedly connected to the upper end of the anchor rod 102; the base 101 and the anchor rod 102 are connected by threads; the base 101 provides an installation position for components such as the anchor rod 102 and the frame 201, and the base 101 is fixed to the ground at a certain height by the anchor rod 102 that can be screwed into the ground to a certain depth, and the anchor rod 102 is conveniently rotated by the rotary handle 103.

[0029] In this embodiment: the elevation component 2 includes a suspension member that can enter the backfill area at a certain distance outside the main body of the device, and can be a marking member for the long-distance elevation within the main body of the device. The suspension member includes a frame 201 movably connected to the base 101, and the upper end of the frame 201 is movably connected to a first electric push rod 202, and the telescopic end of the first electric push rod 202 is fixedly connected to a joint 203, and a suspension rope 204 is fixedly connected below the joint 203, and a elevation is fixedly connected below the suspension rope 204. The plate 205, the marking part includes a support 206 fixedly installed in the frame 201, a lead screw 207 is movably connected between the supports 206, a motor 208 is fixedly connected to the lower end of the lead screw 207, a lifting frame 209 is arranged between the frame 201 and the lead screw 207, a laser transmitter 210 is fixedly installed in the lifting frame 209, and the elevation component 2 also includes a ruler 211 fixedly connected to the front and rear sides of the frame 201, and a level bubble 212 is fixedly connected to the front and rear sides of the lifting frame 209;

[0030] The base 101 and the first electric push rod 202 are both rotatably connected to the frame 201, the support 206 is rotatably connected to the lead screw 207, the frame 201 is slidably connected to the lifting frame 209, the lead screw 207 is threadedly connected to the lifting frame 209, and the emission end of the laser emitter 210 faces the elevation plate 205;

[0031] The frame 201 drives the first electric push rod 202 installed above it and the lifting frame 209 and other components therein to rotate relative to the base 101. The first electric push rod 202 adjusts the distance between the joint 203 and the main body of the device, so that the elevation plate 205 set below the joint 203 through the suspension rope 204 can be adjusted by the first electric push rod 202, so that the horizontal distance between the elevation plate 205 and the laser emitter 210 can be adjusted. The elevation plate 205 that can be suspended in the air enters the short-distance elevation in the backfill area, and the motor 208 drives the lead screw 207 installed in the frame 201 by the support 206 to rotate. The rotating lead screw 207 drives the lifting frame 209 to slide and rise relative to the frame 201, and the laser emitter 210 installed in the lifting frame 209 emits laser to obtain the long-distance elevation outside the backfill area. The specific height of the lifting frame 209 in the frame 201 is displayed by the ruler 211, and the horizontal degree of the lifting frame 209 is displayed by the level bubble 212.

[0032] In this embodiment: the adjustment component 3 includes a second electric push rod 301 movably installed between the base 101 and the frame 201, and a third electric push rod 302 is movably installed between the frame 201 and the first electric push rod 202; the base 101 and the frame 201 are both rotatably connected to the second electric push rod 301, and the frame 201 and the first electric push rod 202 are both rotatably connected to the third electric push rod 302; the frame 201 is driven to rotate relative to the base 101 by the second electric push rod 301 to adjust the verticality of the frame 201, and the first electric push rod 202 is driven to rotate relative to the frame 201 by the third electric push rod 302 to adjust the angle of the first electric push rod 202 relative to the frame 201.

[0033] Working principle: When the device is installed and used for earth backfill elevation work related to infrastructure projects, the base 101 is fixed to the ground at a certain height outside the backfill area through the anchor rod 102, and then the level of the lifting frame 209 is adjusted through the operation of the second electric push rod 301. During the adjustment, the level of the lifting frame 209 can be judged according to the position of the bubble in the level bubble 212. After the adjustment is completed, the elevation plate 205 can enter the backfill area and hover at a certain height in the backfill area according to the height of the foundation ground (the bottom surface of the backfill soil) through the coordinated work of the first electric push rod 202 and the third electric push rod 302. The hovering height of the elevation plate 205 should be based on the height difference from the lower side of the elevation plate 205 to the foundation ground equal to the required backfill height;

[0034] After that, the horizontal height of the laser emitted by the laser emitter 210 can be adjusted by running the motor 208, so that the height of the laser is flush with the smallest diameter of the outer side of the elevation plate 205. When the elevation plate 205 needs to be elevated at different positions of the backfill area later, it is only necessary to switch the position of the elevation plate 205 again through the operation of the first electric push rod 202 and the third electric push rod 302, and make the smallest diameter of the outer side flush with the laser emitted by the laser emitter 210, so that the elevation can be accurately elevated again through the elevation plate 205;

[0035] Similarly, the elevation plate 205 can be retracted after the backfilling begins, and during the backfilling process, the first electric push rod 202 and the third electric push rod 302 can work to place the elevation plate 205 on the surface of the filled area in the backfilling area with the suspension rope 204 hanging normally. Thereafter, the height of the laser irradiated on the elevation plate 205 can be used to quickly determine whether the backfill height of the area contacted by the elevation plate 205 meets the standard.

[0036] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
