[0023] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connection relationships of the components involved, the functions and working principles of the components, etc., by referring to the accompanying drawings:

[0024] As attached Figure 1 , Attachment Figure 2As shown, the utility model is a P-type clamp fastening device for rail transit vehicles, including an upper assembly 1 and a lower assembly 2, the middle of the upper assembly 1 and the middle of the lower assembly 2 are movably hinged, the front of the upper assembly 1 is an upper clamp 3, the front of the lower assembly 2 is a lower clamp 4, the rear of the upper assembly 1 is an upper handle 5, the rear of the lower assembly 1 is a lower handle 6, the rear of the upper clamp 3 is movably hinged with the upper handle 5, the upper handle 5 is movably screwed with an adjusting rod 7, and the front end of the adjusting rod 7 is movably hinged to the upper clamp 3. The above structure proposes an improved technical solution to address the deficiencies in the prior art. When the structure is set, the upper component 1 and the lower component 2 of the device are set, and the middle of the upper component 1 and the middle of the lower component 2 of the device are movably hinged, and the two can realize relative position change, and the front of the upper component 1 of the device is the upper clamp 3, the front of the lower component 2 of the device is the lower clamp 4, the front of the lower component 2 of the device is the lower clamp 4, the rear of the upper component 1 of the device is the upper handle 5, and the rear of the lower component 1 of the device is the lower handle 6. In this way, when the upper handle 5 and the lower handle 6 are operated to approach, the upper clamp 3 and the lower clamp 4 are driven to approach each other, and when the upper handle 5 and the lower handle 6 are operated to move away from each other, the upper clamp 3 and the lower clamp 4 are driven to move away from each other. The rear of the upper clamp 3 is movably hinged with the upper handle 5, and the adjusting rod 7 is movably screwed inside the upper handle 5. The front end of the adjusting rod 7 is movably hinged with the upper clamp 3. In this way, when the adjusting rod is rotated relative to the upper handle, the relative position of the upper handle and the upper clamp can be adjusted. When performing the P-type clamp tightening operation, for bolts of different lengths, first rotate the adjustment rod relative to the upper handle to adjust the relative position of the upper handle and the upper clamp, thereby increasing the application range of the device. Then, the device is placed close to the P-type clamp position of the chassis, and the operator holds the upper handle 5 and the lower handle 6, and the upper clamp 3 is pressed against the tail end of the chassis bolt 12, and the opening of the lower clamp 4 passes through the chassis bolt 12 and is located outside the P-type clamp 11. Then the operator applies force to the upper handle 5 and the lower handle 6, and the upper handle 5 and the lower handle 6 are close to each other, thereby driving the upper clamp 3 and the lower clamp 4 to approach each other, and the upper clamp 3 and the lower clamp 4 generate opposite directions and close forces, which act on the P-type clamp 11, driving the originally open part of the P-type clamp 11 to approach, thereby achieving tightening. The device of the utility model can be used in narrow spaces. As long as it is close to the P-type clamp, the operation can be completed quickly. Moreover, the clamping device is labor-saving and fast, which reduces the labor intensity of the operator and improves the operating efficiency. The P-type clamp fastening device for rail transit vehicles described in the utility model has a simple structure. After the P-type clamp is installed in place, the P-type clamp can be reliably closed, which is convenient for operation in narrow spaces, improves efficiency and reduces labor intensity.

[0025] The upper clamp 3 of the upper component 1 of the device is a sheet structure; the lower clamp 4 of the lower component 2 of the device is a U-shaped sheet structure. In the above structure, when working, the bottom frame bolt passes through the P-type clamp, the bottom end of the bottom frame bolt is screwed with the bottom frame nut, and the upper clamp 3 fits the tail end of the bottom frame bolt, the bottom bolt is located in the U-shaped opening of the lower clamp 4, and then the upper clamp and the lower clamp apply force to conveniently and quickly complete the closing of the P-type clamp and complete the tightening operation.

[0026] A spring 8 is provided between the upper handle 5 and the lower handle 6. With the above structure and the provision of the spring, after the operation is completed, the spring is realized on the upper handle and the lower handle, so that the upper handle and the lower handle are separated and reset, so that the device is convenient to be removed from the P-type clamp position.

[0027] The rear part of the lower clamp 4 is fixedly connected to the front part of the lower handle 6. In the above structure, the lower clamp and the lower handle do not need to be adjusted, but only the upper clamp and the upper handle need to be adjusted.

[0028] The upper handle 5 has a hollow screw hole structure inside, and the adjusting rod 7 has a threaded structure, and the adjusting rod 7 is movably screwed into the inner screw hole structure. With the above structure, when the adjusting rod is rotated relative to the upper handle, the relative position of the upper handle and the upper clamp can be adjusted, thereby adjusting the distance between the upper clamp and the lower clamp, and adjusting the distance between the two in advance. In this way, for P-type clamps of different models and sizes, it can be ensured that the upper clamp and the lower clamp are slightly larger than the required P-type clamp before tightening and applying force, thereby reducing the range of motion of the upper clamp and the lower clamp, avoiding the formation of an excessively large area that causes inconvenience to the operator, and effectively improving convenience.

[0029] The upper clamp 3 is an N-shaped structure, and the lower clamp 4 is an L-shaped structure. The lower end of the upper clamp 3 is hinged to the upper end of the lower clamp 4 through a connecting pin 9. The rear of the upper clamp 3 is located above the connecting pin 9 and is hinged to the adjusting rod 7 through a second connecting pin 10. In the above structure, when the tail end of the adjusting rod is adjusted, the adjusting rod rotates relative to the upper handle, thereby changing the relative position with the adjusting rod. The upper bracket uses the connecting pin as a fulcrum, and through the force of the adjusting rod, the distance between the upper clamp and the lower clamp is driven to change, thereby achieving pre-adjustment.

[0030] The length of the adjusting rod 7 is greater than that of the upper handle 5. Both ends of the adjusting rod 7 are located outside the upper handle 5. In the above structure, the rear end of the adjusting rod is equipped with an adjusting end for easy adjustment, and the front end of the adjusting rod is movably connected to the upper end clamp to meet the pre-adjustment requirements.

[0031] Flexible gaskets are respectively provided on the lower surface of the upper clamp 3 and the upper surface of the lower clamp 4. The above structure prevents surface damage to the contact parts such as the P-type clamp during the clamping process.

[0032] The outer part of the upper handle 5 and the outer part of the lower handle 6 are respectively wrapped with rubber sleeves.

[0033] The rail transit vehicle P-type clamping fastening device described in the utility model is provided with an upper component 1 and a lower component 2 of the device. The middle part of the upper component 1 of the device and the middle part of the lower component 2 of the device are movably hinged, and the two can realize relative position change. The front part of the upper component 1 of the device is an upper end clamp 3, the front part of the lower component 2 of the device is a lower end clamp 4, the front part of the lower component 2 of the device is a lower end clamp 4, the rear part of the upper component 1 of the device is an upper handle 5, and the rear part of the lower component 1 of the device is a lower handle 6. In this way, when the upper handle 5 and the lower handle 6 are operated to be close to each other, the upper end clamp 3 and the lower end clamp 4 are driven to be close to each other, and when the upper handle 5 and the lower handle 6 are operated to be far away from each other, the upper end clamp 3 and the lower end clamp 4 are driven to be far away from each other. The rear part of the upper clamp 3 is movably hinged with the upper handle 5, and the adjusting rod 7 is movably screwed inside the upper handle 5. The front end of the adjusting rod 7 is movably hinged with the upper clamp 3. In this way, when the adjusting rod is rotated relative to the upper handle, the relative position of the upper handle and the upper clamp can be adjusted. When performing the P-type clamp tightening operation, for bolts of different lengths, the adjusting rod is first rotated relative to the upper handle to adjust the relative position of the upper handle and the upper clamp, thereby increasing the application range of the device. Then, the device is brought close to the P-type clamp position of the chassis, and the operator holds the upper handle 5 and the lower handle 6, and the upper clamp 3 is pressed against the tail end of the chassis bolt 12, and the opening of the lower clamp 4 passes through the chassis bolt 12 and is located outside the P-type clamp 11. Then the operator applies force to the upper handle 5 and the lower handle 6, and the upper handle 5 and the lower handle 6 are brought close to each other, thereby driving the upper clamp 3 and the lower clamp 4 to approach each other, and the upper clamp 3 and the lower clamp 4 generate opposite directions and close forces, which act on the P-type clamp 11, driving the originally opened part of the P-type clamp 11 to approach, and achieve tightening. The device of the utility model can be used in a narrow space, and the operation can be completed quickly as long as it is close to the P-type clamp, and the clamping of the device is labor-saving and fast, which reduces the labor intensity of the operator and improves the operation efficiency.

[0034] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
