Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering transportation, and in particular relates to a steel cage mobile trolley. Background Art

[0002] With the rapid development of the national economy, the construction of retaining piles, engineering piles, ground-anchored walls and other projects has emerged one after another. The construction period is tight and the task is heavy. The production of a large number of steel cages has become a difficulty that plagues the construction. The steel cages need to be manufactured and welded at the processing site and then transported to the pile foundation construction site. However, due to the large weight of the steel cages, it is difficult to move the steel cages manually at the construction site. Therefore, some small steel cages will be transported using mobile carts. For example, a mobile cart for steel cages is proposed in patent announcement number CN220997893U.

[0003] When transporting the steel cage, the overall weight of the mobile trolley is large, and some roads on the construction site have insufficient road bearing capacity due to poor mechanical properties of the foundation soil and substandard compaction technology. When the weight of the trolley exceeds the road bearing capacity, it will cause the road surface to sink, causing the trolley to tilt. If the tilt angle exceeds 5°, the mobile trolley will face the risk of overturning, which may cause the steel cage to fall off the vehicle, not only causing the steel cage to deform, but also easily causing casualties, posing a serious safety hazard.

[0004] Therefore, a steel cage mobile trolley is proposed to solve the above problems. Summary of the Invention

[0038] The conveying assembly 24 is fixedly connected to the upper side wall of the support plate 5 and is used to fix and move the steel cage. The conveying assembly 24 includes a linear screw module 241 fixedly connected to the upper side wall of the support plate 5.

Part of the steel cage is located between the locking block 242 and the locking cover 25, which can move the steel cage.

[0039] Two support components 26 are arranged inside the vehicle body 1 to improve the stability of the mobile trolley. The support component 26 includes a support seat 261. The right side wall of the vehicle body 1 is provided with two accommodating grooves that match the support seat 261. The lower side wall of the support seat 261 is provided with a groove 262. The inner wall of the groove 262 is rotatably connected with an adjustment sleeve 27. The side wall of the adjustment sleeve 27 is fixedly connected with an adjustment cylinder 28.

The end of the adjustment rod 29 extending out of the adjustment cylinder 28 is fixedly connected with an anchor nail 30. The side wall of the adjustment sleeve 27 is fixedly connected with a limiting hole plate 31. The limiting hole plate 31 is fixed in the groove 262 by a limiting pin. The side wall of the groove 262 is provided with two limiting holes that match the limiting pin, thereby improving the stability of the placement of the mobile trolley.

[0040] The right side wall of the vehicle body 1 and the front side wall of the support seat 261 at the rear side are fixedly connected to a marking frame 32, and the side wall of the marking frame 32 is fixedly connected to a marking motor 33. The output end of the marking motor 33 is located in the marking frame 32 and is fixedly connected to a laser light 34, which can assist the operator to place the mobile cart in the correct position.

[0041] The operating principle of the present invention is described as follows: the reinforcement cage is placed between the two arc-shaped seats 6 by external lifting equipment (e.g., a crane), and a portion of the reinforcement cage is brought into contact with the locking block 242. Next, the operator secures the locking cover 25 with bolts, and secures the reinforcement cage with the locking cover 25 and the locking block 242. Next, the vehicle body 1 and the external traction vehicle are connected together by the traction frame 3, and the external traction vehicle is then used to drive the mobile trolley and the reinforcement cage toward the pile hole.

[0042] Before the external traction vehicle starts, the operator sends an electric signal to the controller 4 through the external remote control device. After receiving the electric signal, the controller 4 will control the adjustment of the electric push rod 16 to work. The adjustment of the electric push rod 16 will drive the detection cylinder 17 and the contact wheel 19 to move downward to the set position. When the external traction vehicle drives the mobile trolley to move, the mobile trolley will drive the detection wheel 10 to move through the traction plate 2. The friction between the ground and the detection wheel 10 causes the roller part and the wheel shaft of the detection wheel 10 to rotate, and the wheel shaft is driven by the pulley transmission mechanism. The rotating rod 92 is driven to rotate, and the rotating rod 92 drives the cam 11 to rotate. When the raised part of the cam 11 rotates to the bottom, the raised part of the cam 11 presses down the extrusion plate 15, and the extrusion plate 15 drives the lifting rod 13, the adjusting electric push rod 16, the detection cylinder 17 and the contact wheel 19 to move downward together. When the contact wheel 19 contacts the ground, the contact wheel 19 drives the detection pin 18 and the fixed plate 20 to stop moving, and the detection cylinder 17 continues to move downward under the push of the lifting rod 13, so that the fixed plate 20 drives the conductive frame 21 in the detection cylinder 17. The contact wheel 19 moves relatively upward. Since the middle part of the contact wheel 19 is a raised structure, when the road surface support force is insufficient and relatively soft, under the tension of the spring between the fixing plate 20 and the detection cylinder 17, the contact wheel 19 will be inserted into a deeper position of the ground. When the raised part of the cam 11 moves to the lowest end, the trigger switch 23 inside the cam 11 will be pressed by the extrusion plate 15, and the lifting rod 13 will drive the detection cylinder 17 to move downward to the lowest end. When the trigger switch 23 is pressed, the trigger switch 23 will control the conductive frame 21 and the inside of the vehicle body 1 through the controller 4. The contact wheel 19 is located at a deeper position in the ground due to insufficient road bearing capacity. When the detection tube 17 moves downward to the lowest end, the conductive frame 21 will not contact the conductive plate 22. Therefore, when the controller 4 does not receive the electrical signal transmitted by the conductive plate 22 within 0.5 seconds after receiving the electrical signal transmitted by the trigger switch 23, the controller 4 will remind the operator to stop towing the mobile trolley through the internal buzzer module to avoid the mobile trolley from tipping over due to insufficient road bearing capacity and road subsidence, which poses a greater safety hazard.

[0043] After the steel cage is transported to the vicinity of the pile hole by the mobile trolley, the operator extracts the two support bases 261 from the vehicle body 1. Then, the operator transmits an electrical signal to the controller 4 through the remote control device. After receiving the electrical signal, the controller 4 controls the two marking motors 33 and the two laser lights 34 to work simultaneously. The marking motor 33 drives the laser lights 34 to rotate. Figure 7As shown, the light beam emitted by the laser lamp 34 on the right side of the vehicle body 1 is horizontal, and the light beam emitted by the laser lamp 34 in front of the support seat 261 at the rear side is longitudinal. The laser beams emitted by the two laser lamps 34 will intersect on the ground. By adjusting the position of the mobile trolley, the intersection of the two laser beams is roughly at the center of the pile hole (the intersection is invisible at the center of the pile hole, and the intersection of the laser beams can be judged by the paths of the two laser beams passing through the center of the pile hole). Then, the operator takes out the limit pin, and then rotates the adjustment cylinder 28 to the vertical state, and continues to use the limit pin to fix the adjustment cylinder 28 in the vertical state. Then the operator rotates the adjustment rod 29, and through the threaded cooperation of the adjustment cylinder 28 and the adjustment rod 29, the adjustment rod 29 drives the anchor 30 to be inserted into the ground. When all the adjustment rods 2 9 After all are adjusted, the operator needs to pull the locking pin 38 to release the fixation between the locking frame 36 and the locking seat 37. Then, the operator uses the remote control device to send an electrical signal to the controller 4. After receiving the electrical signal, the controller 4 will control the multi-stage hydraulic cylinder 8 to work. The multi-stage hydraulic cylinder 8 will drive the support plate 5 to rotate, so that the support plate 5 drives the arc seat 6 and the steel cage to be in a vertical state, and makes the center of the steel cage located at the intersection of the two laser beams, that is, the center of the pile hole. Then the controller 4 controls the linear screw module 241 to work. The linear screw module 241 drives the steel cage downward through the locking block 242 and the locking cover 25, so that the steel cage is inserted into the pile hole. When the steel cage is placed, the locking cover 25 is manually removed to release the fixation between the locking block 242 and the steel cage.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
