Description

Technical Field

[0001] This utility model relates to the field of automobile handling technology, and in particular to a telescopic clamping automobile handling trolley. Background Technology

[0002] When parking in an intelligent automated parking garage, a car-car ... Summary of the Invention

[0003] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a telescopic clamping car transport trolley. The clamping mechanism of the transport trolley clamps the car tire by first extending laterally and then clamping it horizontally in the longitudinal direction, so as to realize the car transport function. The transport trolley has a stable and reliable structure and can reduce the clamping damage to the car tire.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A telescopic clamping car transport trolley includes:

[0006] The platform has a longitudinal traveling mechanism installed at its bottom.

[0007] The clamping mechanism is provided in two sets. Each set of clamping mechanisms includes a longitudinal mounting beam and two clamping arms arranged in the transverse direction. One end of each clamping arm is installed on the same side of the longitudinal mounting beam through a first telescopic mechanism. The first telescopic mechanism drives the two clamping arms to extend and retract synchronously along the longitudinal mounting beam, so that the two clamping arms move closer or further away. The longitudinal mounting beams of the two sets of clamping mechanisms are symmetrically installed on both sides of the platform through a second telescopic mechanism, and the clamping arms of the two sets of clamping mechanisms face outwards from the platform. The second telescopic mechanism drives the two sets of clamping mechanisms to extend and retract synchronously in the transverse direction of the platform.

[0008] The first telescopic mechanism is a bidirectional electric push rod, which is fixed longitudinally to the longitudinal mounting beam. The two telescopic ends of the bidirectional electric push rod are respectively fixedly connected to two clamping arms, driving the clamping arms to telescopically extend and retract synchronously along the longitudinal direction.

[0009] The upper surfaces of the clamping arms are all inclined toward the other clamping arm in the same clamping mechanism, and rollers arranged in a transverse direction are installed on the inclined surfaces of the clamping arms.

[0010] The outer side of each longitudinal mounting beam is fixedly connected to a support frame below the clamping arm. Rollers arranged laterally are installed at the bottom of the clamping arm, and the rollers at the bottom of the clamping arm are supported on the support frame.

[0011] The second telescopic mechanism includes a drive motor, a driving gear, a driven gear, a rack, and telescopic rods. The drive motor is mounted and fixed on the frame. The driving gear is connected to the drive motor. There are two driven gears, racks, and telescopic rods. Both driven gears are rotatably mounted on the frame. One driven gear directly meshes with the driving gear, and the other driven gear meshes with the driving gear through an idler gear. The two telescopic rods are arranged symmetrically in the transverse direction, and one end of each telescopic rod is fixedly connected to the longitudinal mounting beams of the two clamping mechanisms. The two racks are fixed to the two telescopic rods and mesh with the two driven gears respectively. The drive motor drives the driving gear to rotate, causing the two driven gears to rotate synchronously in opposite directions. The two driven gears drive the two racks respectively, thereby causing the two telescopic rods to extend and retract synchronously.

[0012] The second telescopic mechanism is arranged in two sets in parallel, and the drive motors of the two sets of second telescopic mechanisms are driven synchronously through mechanical synchronization and high-precision closed-loop synchronous control.

[0013] The second telescopic mechanism also includes a guide rail and a guide rod arranged in the transverse direction. The guide rail is fixed on the platform, and two guide rods are symmetrically arranged. One end of each guide rod is slidably mounted on the guide rail, and the other end of each guide rod is fixedly connected to the longitudinal mounting beams of the two sets of clamping mechanisms.

[0014] Two guide rails are provided, and the two guide rails are installed alternately on the frame. The two guide rods are slidably installed on the two guide rails respectively.

[0015] The guide rails are arranged in two sets side by side, and the guide rods are arranged in two sets accordingly.

[0016] Two car handling trolleys are provided.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the telescopic clamping car transport trolley provided by this utility model realizes the expansion and retraction of two sets of clamping mechanisms through the first telescopic mechanism, ensuring that the car transport trolley can freely enter and exit the bottom of the car. At the same time, the second telescopic mechanism realizes that the two clamping arms in each set of clamping mechanisms move away from or close to each other, thereby clamping the car tires and realizing the car transport function. Moreover, the overall structure of the transport trolley is stable and reliable.

[0018] (2) In this utility model, the clamping arm is inclined toward the surface of the car tire and is equipped with rollers. When the clamping arm clamps the car tire, it can reduce the damage to the tire. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] The telescopic clamping car handling trolley structure provided in this embodiment is as follows: Figures 1-6 As shown, the system includes a platform 1, a longitudinal traveling mechanism 2, a clamping mechanism 3, a first telescopic mechanism, and a second telescopic mechanism. The longitudinal traveling mechanism is installed at the bottom of the platform and drives the entire platform to travel longitudinally. Specifically, the longitudinal traveling mechanism includes an automatic traveling wheel set and a driven wheel set. The automatic traveling wheel set and the driven wheel set are existing technologies, and their structure and traveling method are not described in detail here.

[0028] The clamping mechanism is provided in two sets. Each set includes a longitudinal mounting beam 31 and two clamping arms 32 arranged laterally. One end of each clamping arm is mounted on the same side of the longitudinal mounting beam via a first telescopic mechanism. The first telescopic mechanism drives the two clamping arms to extend and retract synchronously along the longitudinal mounting beam, causing the two clamping arms to move closer or further apart. Specifically, the first telescopic mechanism is a bidirectional electric push rod 4, which is fixed longitudinally to the longitudinal mounting beam. The two telescopic ends of the bidirectional electric push rod are respectively fixedly connected to the two clamping arms, driving the clamping arms to extend and retract synchronously along the longitudinal direction. The two bidirectional electric push rods and the synchronous control of the two telescopic ends of the bidirectional electric push rods are existing technologies and will not be described in detail here. Specifically, the upper surfaces of the clamping arms are inclined towards the other clamping arm in the same set of clamping mechanisms, and rollers 33 arranged laterally are mounted on the inclined surfaces of the clamping arms. When the two clamping arms clamp the car tire, they can better fit the curved surface of the car tire. See Figure 6 This reduces damage to the tires. Specifically, support frames 34 are fixedly connected to the outer side of the longitudinal mounting beam below the clamping arm. Rollers arranged laterally are also installed at the bottom of the clamping arm. The rollers at the bottom of the clamping arm are supported on the support frames, so that the cantilevered clamping arm is supported on the support frames, increasing the strength of the clamping arm.

[0029] The longitudinal mounting beams of the two clamping mechanisms are symmetrically installed on both sides of the platform via a second telescopic mechanism, with the clamping arms of both mechanisms facing outwards from the platform. The second telescopic mechanism drives the two clamping mechanisms to extend and retract synchronously along the lateral side of the platform, allowing them to retract or extend. It is important to note that when the two clamping mechanisms are retracted, the maximum width between them is less than the distance between the left and right tires of the vehicle, ensuring that the car handling trolley can freely access the underside of the vehicle to be transported.

[0030] In this embodiment, the second telescopic mechanism includes a drive motor 51, a driving gear, a driven gear, a rack, a telescopic rod 52, a guide rail 53, and a guide rod 54. The drive motor is mounted and fixed on the frame. The driving gear is connected to the drive motor. Two driven gears, racks, and telescopic rods are provided. Both driven gears are rotatably mounted on the frame. One driven gear directly meshes with the driving gear, and the other driven gear meshes with the driving gear through an idler gear. Two telescopic rods are arranged symmetrically in the transverse direction, and one end of each rod is fixedly connected to the longitudinal mounting beams of the two clamping mechanisms. Two racks are fixed to the two telescopic rods and mesh with the two driven gears respectively. The guide rail is fixed in the transverse direction on the frame. Two guide rods are symmetrically arranged, and one end of each rod is slidably mounted on the guide rail. The other ends of each rod are fixedly connected to the longitudinal mounting beams of the two clamping mechanisms. Specifically, two guide rails are provided, and they are staggered vertically on the frame. Figure 2Two guide rods are slidably mounted on two guide rails, thereby increasing the overlap length of the guide rods and guide rails and enhancing the structural stability of the second telescopic mechanism. Further, sliding blocks or sliding wheel sets are connected to the guide rods, and these blocks or sets are installed within slide tracks on the guide rails. A drive motor drives the driving gear to rotate, causing two driven gears to rotate synchronously in opposite directions. The two driven gears each drive two racks, thereby causing the two telescopic rods to extend and retract synchronously. The two guide rods also extend and retract synchronously along the guide rails, thus causing the two sets of clamping mechanisms to extend and retract synchronously. Further, two sets of guide rails are arranged side-by-side, and two sets of guide rods are correspondingly arranged, further enhancing the structural stability of the second telescopic mechanism. Preferably, the drive motor is a geared motor. Preferably, the driven gears are gear shafts. In a preferred embodiment, two sets of second telescopic mechanisms are arranged in parallel to further enhance structural stability. The drive motors of the two sets of second telescopic mechanisms can be synchronously driven by means of mechanical synchronization, high-precision closed-loop synchronous control, etc. Synchronous driving of drive motors by means of mechanical synchronization, high-precision closed-loop synchronous control, etc. is existing technology and will not be described in detail here.

[0031] In this embodiment, two car-moving trolleys are used in conjunction with each other and employ laser positioning or visual recognition technology to detect the vehicle's wheelbase in real time and automatically identify the positions of the front and rear tires. This allows the two trolleys to be positioned under the vehicle and clamp the front and rear tires respectively, thus achieving the car-moving function. Laser positioning or visual recognition technology for identifying the front and rear tire positions is existing technology and will not be described in detail here.

[0032] The working method of the telescopic clamping car handling trolley provided in this embodiment is as follows: The initial state of the car handling trolley is as follows: Figure 1 As shown, at this time, both sets of clamping mechanisms are in the retracted state, and the two clamping arms of each set are in the extended state, ensuring that the transport trolley can smoothly enter the bottom of the car to be transported, and that the clamping arms will not collide with the car tires when the two sets of clamping mechanisms are extended. After receiving the transport command, the two transport trolleys automatically identify the positions of the front and rear tires of the car and enter the corresponding positions under the car. After the transport trolleys enter the designated positions, the second telescopic mechanism drives the two sets of clamping mechanisms to extend, so that the two clamping arms of each set are located at the front and rear of the lower part of the tire, as shown. Figure 3 and Figure 4 As shown. The first telescopic mechanism synchronously drives the two clamping arms of each clamping mechanism to move longitudinally closer and clamp the lower front and rear parts of the car tire, as shown. Figure 5 and Figure 6 As shown. Then, the transport trolley moves the car into the designated position in the automated parking garage. The first telescopic mechanism synchronously drives the two clamping arms of each clamping mechanism to open and lower the car. The second telescopic mechanism drives the two clamping mechanisms to retract, as shown. Figure 1As shown, the transport trolley can now be driven away from under the car to complete the storage process.
