[0002] Engineering equipment refers to electromechanical equipment, metal structural equipment, instruments and other similar equipment and devices that constitute or are planned to constitute part of a permanent project. During engineering operations, engineering personnel often need to carry various engineering equipment to and from the construction site, thus requiring the transportation of engineering equipment.

[0003] Engineering equipment is usually transported by truck. During the transport process, the equipment is usually moved onto the truck by manpower or placed on a ramp and then pushed onto the truck by manpower. However, both of these methods are not only inefficient, but also waste a lot of manpower. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a chassis for engineering equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A chassis for engineering equipment includes a carrier plate. Hanging assemblies are provided on both sides of the carrier plate. Two telescopic rods are fixedly connected to the bottom of each end of the carrier plate. A fixed plate is fixedly connected to the bottom between the two telescopic rods. Two fixed blocks are fixedly connected to the upper surface of the carrier plate. A connecting shaft is movably connected between the two fixed blocks. A power assembly for driving the connecting shaft to rotate is provided on the upper surface of the carrier plate. Take-up and release rollers are fixedly connected to both ends of the connecting shaft. A second pull rope is wound around the outer side of the take-up and release rollers. A slide cylinder is fixedly connected to the bottom of the carrier plate. A slide rod is fixedly connected to the upper surface of the fixed plate, and the slide rod is slidably connected to the slide cylinder. A guide roller is fixedly connected to the bottom of the slide cylinder. A first clearance groove is formed inside the slide rod, and one end of the second pull rope passes around the guide roller and enters the first clearance groove, fixing it to the top inner wall of the slide cylinder. Two casters are fixedly connected to the bottom of the fixed plate.

[0007] As a further embodiment of this utility model, the power assembly includes a support frame, which is fixed to the upper surface of the carrier plate by bolts. A worm gear is movably connected to one inner wall of the support frame, and a motor is fixedly connected to one outer wall of the support frame. One end of the motor output shaft is fixed to the worm gear, and a worm wheel is keyed to the outer side of the middle position of the connecting shaft, and the worm wheel meshes with the worm gear.

[0008] As a further embodiment of this utility model, the hanging assembly includes a plurality of first pull ropes, which are symmetrically installed on both sides of the carrier plate, and the bottom end of the first pull rope is provided with a hook.

[0009] As a further improvement of this invention, a baffle is movably connected to one side of the hook opening.

[0010] As a further embodiment of this utility model, both ends of the baffle pass through the hook and are fitted with torsion springs, and the two ends of the torsion springs are fixed to the hook and the baffle respectively.

[0011] As a further improvement of this utility model, a second clearance groove is provided on one side of the slide cylinder.

[0012] As a further improvement of this utility model, the universal wheels are symmetrically distributed.

[0013] The beneficial effects of this utility model are as follows:

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0023] Reference Figures 1-4 A chassis for engineering equipment includes a carrier plate 7. Hanging assemblies are provided on both sides of the carrier plate 7. Two telescopic rods 9 are bolted to the bottom of each end of the carrier plate 7. A fixing plate 11 is bolted to the bottom between the two telescopic rods 9. The telescopic rods 9 guide the carrier plate 7 to prevent it from tilting during movement. Two fixing blocks 2 are bolted to the upper surface of the carrier plate 7. A connecting shaft 3 is rotatably connected between the two fixing blocks 2. A power assembly for rotating the connecting shaft 3 is provided on the upper surface of the carrier plate 7. Take-up and release rollers 1 are bolted to both ends of the connecting shaft 3. A second pull rope 12 is wound around the outside of the take-up and release rollers 1. The power assembly rotates the connecting shaft 3, thereby causing the take-up and release rollers 1 to wind up the second pull rope 12. A slide cylinder 16 is bolted to the bottom of the carrier plate 7. A slide rod 17 is bolted to the upper surface of the fixing plate 11, and the slide rod 17 is slidably connected to the slide cylinder 16. The bottom of the slide cylinder 16 is fixed with a guide roller 19 by bolts. The slide rod 17 has a first clearance groove 18 inside. One end of the second pull rope 12 passes around the guide roller 19 and enters the first clearance groove 18 and is fixed to the top inner wall of the slide cylinder 16. The bottom of the fixing plate 11 is fixed with two universal wheels 10 by bolts. The universal wheels 10 are symmetrically distributed. Since the other end of the second pull rope 12 is fixed to the slide rod 17, the slide cylinder 16 slides upward along the slide rod 17 while the take-up and release roller 1 is winding up. This causes the carrier plate 7 to move the engineering equipment hooked by the hook 14 upward to the required height. At the same time, the telescopic rod 9 extends and pushes the device. The universal wheels 10 drive the device to move the whole device to the truck bed. At this time, the height of the carrier plate 7 is higher than the truck bed, and the distance between the two fixing plates 11 exceeds the width of the truck bed. Then the take-up and release roller 1 is unwound so that the engineering equipment falls into the truck bed and separates from the hook 14.

[0024] In this utility model, it should be noted that the power assembly includes a support frame 6, which is fixed to the upper surface of the carrier plate 7 by bolts. A worm gear 5 is rotatably connected to one inner wall of the support frame 6, and a motor is fixed to one outer wall of the support frame 6 by bolts. One end of the motor output shaft is fixed to the worm gear 5. A worm wheel 4 is keyed to the outer side of the middle position of the connecting shaft 3, and the worm wheel 4 meshes with the worm gear 5. The rotation of the motor causes the worm gear 5 to rotate, thereby causing the worm wheel 4 to drive the connecting shaft 3 to rotate. The suspension assembly includes multiple first pull ropes 8, which are symmetrically installed on both sides of the carrier plate 7. The bottom end of the 8 is provided with a hook 14, which hooks the lifting ring on the engineering equipment to facilitate the subsequent suspension and movement of the engineering equipment. A baffle 13 is rotatably connected to one side of the opening of the hook 14. Both ends of the baffle 13 pass through the hook 14 and are fitted with torsion springs 15. The two ends of the torsion springs 15 are fixed to the hook 14 and the baffle 13 respectively. The baffle 13 can block the opening of the hook 14 to prevent the lifting ring on the engineering equipment from easily detaching from the hook 14, making it safer to use. A second clearance groove 20 is provided on one side of the slide cylinder 16 to avoid the second pull rope 12.

[0025] Working principle: When it is necessary to transfer engineering equipment, firstly, hook 14 is hooked onto the lifting ring on the engineering equipment. The opening of hook 14 is blocked by the action of baffle 13 and torsion spring 15. Then, the motor is started. The motor rotates and the worm gear 5 rotates, which in turn drives the connecting shaft 3 to rotate. This causes the take-up roller 1 to wind up the second pull rope 12. Since the other end of the second pull rope 12 is fixed to the slide rod 17, the slide cylinder 16 slides upward along the slide rod 17 while the take-up roller 1 is winding up. This causes the carrier plate 7 to move the engineering equipment hooked by hook 14 upward to the required height. At the same time, the telescopic rod 9 extends and pushes the device. The universal wheel 10 drives the entire device to move to the truck bed. Then, the take-up roller 1 is unwound, so that the engineering equipment falls into the truck bed and separates from hook 14.
