Top car

The invention relates to a jacking machine.

Press, the general top car machine is used to lift the vehicle to facilitate maintenance. In order to save space, the top car machine will be installed in a pit. When the top car is lowered, the carrying platform of the top car will be Parallel to the ground, to facilitate vehicle travel and staff walking, when the top lift is raised, the load platform will be higher than the pit, the staff can stand under the load platform for vehicle maintenance, the top of TWI259826 This is the case with the car.

However, such a conventional top-loading machine has the following problems. When the top-lifting machine is raised, the pit will be exposed. If the staff is performing maintenance work under the roof, it is easy to step on the ground due to the pit, causing the drop. To the pit, it is easy to cause accidents such as casualties, and there are defects that need to be improved.

Therefore, it is necessary to provide a novel and progressive top car to solve the above problems.

The main object of the present invention is to provide a jacking machine comprising a first lifting device and a second lifting device. When the first lifting device is raised, the second lifting device is raised and shielded. The opening of the pit to avoid accidentally falling into the pit.

In order to achieve the above object, the present invention provides a jacking machine for a pit provided, the jacking machine comprising a first lifting device, a second lifting device and a sensing device. The first lifting device is disposed at the pit and can be selectively raised and lowered in a raised position and a folded position. The second lifting device is vertically disposed at the pit. The sensing device is configured to detect the lifting of the first lifting device. When the sensing device detects that the first lifting device is raised from the folding position toward the rising position, the second lifting device is raised to shield The opening of the pit; when the sensing device detects that the first lifting device is lowered from the raised position toward the folding position, the second lifting device descends to the bottom of the pit.

In order to achieve the above object, the present invention further provides a jacking machine for providing a pit, the pit comprising two parallel spaced receiving slots and a passage connecting the two receiving slots, the jacking machine includes a A first lifting device, a second lifting device and a sensing device. The first lifting device includes a first lifting frame that is moved in parallel and a connecting piece connected to the two first lifting frames. The two first lifting frames are respectively disposed in the two receiving slots, and the first two The lifting device can be selectively raised and lowered in a raised position and a folded position. When the two first lifting frames are in the folding position, the connecting member is located in the receiving groove, when the two first lifting frames are located In the raised position, the connecting member is disengaged from the receiving groove. The second lifting device is vertically disposed in the passage. The sensing device is configured to detect the lifting of the first lifting device. When the sensing device detects that the first lifting device is raised from the folding position toward the rising position, the second lifting device is raised to shield An opening of the passage of the pit; when the sensing device detects that the first lifting device is lowered from the raised position toward the folding position, the second lifting device descends to the bottom of the passage of the pit.

The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Referring to Figures 1 to 8, there is shown a preferred embodiment of the present invention. The top loading machine 1 of the present invention is provided in a pit 9 which includes a first lifting device 2 and a second lifting device Device 3 and a sensing device 4. The first lifting device 2 is disposed in the pit 9 and is selectively movable up and down in a raised position and a folded position. The second lifting device 3 is mounted on the pit 9 in a vertically movable manner. The sensing device 4 is configured to detect the lifting of the first lifting device 2, and when the sensing device 4 detects that the first lifting device 2 is raised from the folding position toward the rising position, the second lifting device 3 is raised to cover the opening of the pit 9 (as shown in FIGS. 4 and 5); when the sensing device 4 detects that the first lifting device 2 is lowered from the raised position toward the folded position The second lifting device 3 descends to the bottom of the pit 9 (as shown in Figures 7 and 8).

Further, in the embodiment, the pit 9 includes two parallel spaced receiving slots 91 and a passage 92 communicating with the two receiving slots 91. The first lifting device 2 includes a first lifting frame 21 that is moved in parallel, and a connecting member 22 that is connected to the two first lifting frames 21. The two first lifting frames 21 are respectively disposed in the two receiving slots. When the two first lifting frames 21 are in the folding position, the connecting member 22 is located in the receiving groove 91. When the two first lifting frames 21 are in the raised position, the connecting member 22 is separated from the The groove 91 is accommodated.

In actual use, when the sensing device 4 detects that the first lifting device 2 is raised from the folded position toward the raised position, the second lifting device 3 is raised to block the passage 92 of the pit 9. Opening to prevent the worker from accidentally falling into the passage 92 when performing maintenance work on the ground; when the sensing device 4 detects that the first lifting device 2 is lowered from the raised position toward the folded position, The second lifting device 3 is lowered to the bottom of the passage 92 of the pit 9 so that the connecting member 22 is not disturbed by the second lifting device 3 and can be smoothly lowered to the passage 92, and the two first lifting frames 21 can be smoothly lowered to the two accommodating slots 91. It should be noted that, in this embodiment, the second lifting device 3 is disposed in the channel 92, and in other embodiments, the second lifting device 3 can be extended to the second receiving slot 91 to prevent the staff from accidentally falling into the second receiving position. Slot 91.

In this embodiment, each of the first lifting frames 21 is provided with a scissor tripod 23 and a carrying board 24, and the connecting member 22 is connected to the two carrying boards 24, and the two carrying boards 24 are for carrying a vehicle.

Preferably, the sensing device 4 is disposed on a scissor stand 23. When the first lifting device 2 is in the folding position, the sensing device 4 is shielded by a carrier plate 24, the second The lifting device 3 does not rise. When the first lifting device 2 is in the raised position, the sensing device 4 is not shielded by the carrying plate 24. The sensing device 4 triggers the second lifting device 3 to rise. Start. It should be noted that in other embodiments, the sensing device 4 can also be disposed on the second lifting device 3, and the sensing device 4 can still sense the first lifting device 2 to trigger the second lifting device 3 to rise or fall.

Preferably, the second lifting device 3 is provided with a baffle 31. When the second lifting device 3 is raised, the baffle 31 shields the opening of the pit 9. In the embodiment, the second lifting device 3 includes a second lifting frame 32 that is moved in two directions, and the two second lifting frames 32 are connected to the baffle 31.

Further, the second lifting frame 32 is provided with a gas pressure bar 33. When the sensing device 4 detects that the first lifting device 2 is raised from the folding position toward the rising position, the two gas pressure bars 33 That is, the second lifting frame 32 can be raised by being inflated and extended. When the sensing device 4 detects that the first lifting device 2 is lowered from the raised position toward the folding position, the air pressure bar 33 That is, it is in a deflated state and can be arbitrarily shortened. Therefore, the gas pressure bar 33 can be automatically deflated to be shortened, or can be deflated by being pressed by the connecting member 22.

In summary, in the jacking machine of the present invention, when the sensing device detects that the first lifting device is raised from the folded position toward the raised position, the second lifting device is raised to cover the pit. Open to prevent staff from accidentally falling into the repair work on the ground.
