Description

Technical Field

[0001] The utility model relates to the technical field of rail transit vehicle interior decoration component installation, in particular to a rail vehicle toilet installation size adjustment device. Background Art

[0002] In the standardized EMU project, the size and verticality of the bathroom are more difficult to adjust than those of the traditional CRH3 type vehicle project, because the bathroom is composed of two combined integral rooms with a length of 2 meters, a width of 1 meter, and a height of 2.36 meters, and weighs 1.5 tons. It is difficult to achieve the qualified size of the bathroom. Secondly, the error of the bathroom floor beam and the error of the bathroom itself lead to the verticality in the four directions of front, back, left, and right not meeting the verticality requirements, which will lead to the following effects:

[0003] 1) Multiple disassembly and assembly is not only time-consuming and labor-intensive, but also cannot guarantee assembly quality, affecting production progress;

[0004] 2) Repeated installation may also cause the risk of scratching the wiring harness and damaging the cold protection;

[0005] 3) The verticality of the bathroom is crucial to the subsequent installation of the flat ceiling;

[0006] The existing technical method is to use an ink line meter and a crowbar to adjust. Since the force of the crowbar is unstable, it is always unqualified after adjustment and needs secondary adjustment. The most important point is that if the crowbar is used too hard, it is easy to squeeze the toilet and crack or damage it, so a stable force output device is needed for adjustment;

[0007] Therefore, in view of the above problems, it is necessary for the utility model to provide a rail vehicle toilet installation size adjustment device capable of adjusting the toilet size to an ideal size. Utility Model Content

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] Figure 1 This is an axonometric diagram of a rail vehicle toilet installation size adjustment device disclosed in the utility model. The adjustment device uses the principle of a hydraulic jack to achieve the extension and retraction of the jack by increasing or decreasing the pressure of a hydraulic pump, thereby adjusting the size. When adjusting the installation size of the toilet, the adjustment device is used in a set of three;

[0029] In the specific embodiment, see Figure 1 , 2 As shown, the rail vehicle toilet installation size adjustment device includes: a base 1, a support rod 2, a telescopic rod 3, a positioning pin 4, a jack 5, a compensation rod 6, a pipeline 7, a handle 8, a hydraulic cylinder 9, and a nut 10;

[0030] The bottom end of the support rod 2 is fixedly connected to the base 1. The support rod 2 is a telescopic rod structure, and its length can be extended and locked to any length. A jack 5 that can be horizontally extended is fixedly connected to the top of the support rod 2. The jack 5 is a hydraulic jack. One end of the pipeline 7 is connected to the jack 5 through a joint, and the other end is connected to the hydraulic cylinder 9 through a joint. The joints are all quick-plug joints in the prior art. The hydraulic cylinder 9 is equipped with a handle 8, and the hydraulic cylinder is opened or closed by the handle 8. A compensation rod 6 is fixedly connected to the jack 5 away from the telescopic end, and a top block 61 is movably connected to the end of the compensation rod 6. When in use, the top block 61 contacts the side wall, and the jack 5 contacts the bathroom and supports the displacement of the bathroom.

[0031] Preferably, the support rod 2 includes a support rod body, a telescopic rod 3 inserted into the support rod body, and a locking member 4. The telescopic rod 3 and the support rod body are slidably connected. A locking hole for installing the locking member 4 is provided at the top of the support rod body. The locking hole is a threaded hole. Preferably, the locking member 4 is a top screw, which is threadedly connected to the support rod body through the threaded hole. A handle is fixedly connected to one end of the top screw to drive the top screw to rotate. When in use, the locking member 4 can extend into the inner cavity of the support rod body and abut against the side wall of the telescopic rod 3 to lock the telescopic height of the telescopic rod 3.

[0032] A threaded hole is formed at the jack 5 away from the telescopic end, and the compensation rod 6 has an external thread. The compensation rod 6 is threadedly connected to the jack 5 through the threaded hole. The compensation rod 6 is sleeved with a locking member, and the compensation rod 6 and the jack 5 are fixedly connected by the locking member. The specific locking member is a nut 10;

[0033] In the above technical solution, the utility model provides a rail vehicle toilet installation size adjustment device, and the method of use is:

[0034] First, assemble the adjustment device;

[0035] Before adjusting the toilet, lift all three sets of adjustment devices and hydraulic devices (not shown) onto the vehicle, and place them on the left side, right side and front of the toilet respectively, and on the wire trough protection plate in the vehicle, raise the telescopic rod 3 to a fixed position, rotate the locking member 4 and lock the position of the telescopic rod 3, follow the compensation rod 6, and adjust the position of the compensation rod 6 so that the top block 61 contacts the wall, lock the nut 10, and then connect the hydraulic cylinder 9, the pipeline 7, and the jack 5. The hydraulic cylinder 9 is connected to the external hydraulic device pipeline. After the connection is completed, use the handle 8 to increase the pressure so that the jack 5 extends and contacts the side wall of the toilet;

[0036] When adjusting the size of a toilet seat:

[0037] One person observes the ruler and the ink line meter, and the other adjusts the toilet installation size adjustment device. Generally, the size of the seated toilet is adjusted first, and the air pressure is increased on the hydraulic cylinder handle 8 placed on the left and front of the toilet to extend the jack 5, the toilet is stressed, and the toilet moves to the right and back. When the size and verticality are qualified, the observer will ask the operator to stop applying pressure and then pre-tighten the bolts of the side wall bracket. After tightening, confirm whether the size and verticality in both directions are qualified.

[0038] When sizing a squat toilet:

[0039] Adjust the size of the squat toilet, increase the air pressure on the hydraulic cylinder handle 8 placed on the right and front of the toilet, extend the jack 5, force the toilet, and move the toilet to the left and back. When the size and verticality are qualified, the observer will ask the operator to stop applying pressure and pre-tighten the bolts of the side wall bracket. After tightening, confirm whether the size and verticality in both directions are qualified.

[0040] After the size adjustment is completed, the air pressure is removed, the pipeline 7 is disassembled, the nut 10 is loosened, the compensation rod 6 is disassembled, the rotating locking piece 4 is away from the telescopic rod 3, the telescopic rod 3 falls into the support rod 2, and all the components are moved out of the car.

[0041] The adjustment device uses a jack to support the toilet, which greatly improves the installation quality and avoids scratches on materials caused by prying the toilet, improves production efficiency, reduces labor intensity, and the thrust is controllable, which not only saves manpower and material resources, but also effectively eliminates the hidden dangers of unqualified toilet size and verticality, and avoids dismantling quality accidents.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
