Description

Technical Field

[0001] This utility model relates to the technical field of overhead contact line equipment for China's high-speed railways, and in particular to a portable pre-installation platform for a high-speed railway overhead contact line positioning device. Background Technology

[0002] The overhead contact system of a high-speed railway is a suspended line above high-speed trains that supplies power to them. It mainly consists of the contact wire, catenary wire, positioning devices, and support devices. According to the design requirements, the contact wire must be fixed in its designed position using positioning devices. These devices can be installed in either a forward or reverse manner. The positioning devices provide horizontal positioning, swing limit, height adjustment, and wind and vibration protection for the contact wire. They must also allow for vertical movement when the train's pantograph is drawing current, and be able to move forward and backward along the track direction as the contact wire expands and contracts with changes in ambient temperature. Since the contact wire is installed horizontally, the positioning clamps, positioning devices, positioning supports, and positioning tubes on the positioning device must be perpendicular to the contact wire to ensure proper operation.

[0003] The positioning device consists of a positioner, a positioning tube, a positioning clamp, a positioning support, a double-ear sleeve, a single-ear sleeve, a rotating double-ear sleeve, a guy wire, a guy wire fixing hook, a windproof guy wire, a windproof guy wire positioning ring, and related connecting parts. If the parts on the positioning device are misaligned, the contact wire design position may change, the positioning clamp may not be able to be installed or may fall off after installation, the positioner may not be able to move back and forth or rise and fall normally, and the contact wire may not be able to be raised to the limit. If this continues for a long time, it may also cause serious consequences such as deformation or breakage of the positioning device and damage to the contact wire.

[0004] Therefore, the installation standards for positioning devices are very high. It must be ensured that all components on the positioning device are in the same vertical horizontal plane and are not tilted.

[0005] Currently, during the installation of high-speed railway overhead contact lines, the positioning devices are assembled manually on the ground. Due to limited pre-installation environmental conditions, it is difficult to achieve a standard installation on the first attempt. Uneven ground and the need for visual alignment are factors contributing to non-standard installation. Generally, multiple readjustments are required after connection to the overhead contact line, and even then, achieving a perfectly vertical alignment cannot be guaranteed. Therefore, the non-standard positioning devices impose a significant workload on workers during high-speed railway construction and maintenance. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the deficiencies and defects mentioned in the background art above, and to provide a portable pre-installation platform for a high-speed rail catenary positioning device that can accurately locate the catenary. To solve the above technical problem, the technical solution proposed by this utility model is as follows:

[0007] A portable pre-installation platform for a high-speed rail contact network positioning device includes: a positioning fixing platform and a double-ear sleeve fixing platform used in conjunction. The positioning fixing platform is used to fix the positioning tube and the positioning device. The positioning fixing platform includes a support base, a fixing base plate fixed to the support base, and positioning tube fixing components and positioning device fixing components arranged opposite to each other on the fixing base plate. The positioning tube fixing component includes two positioning tube fixing grooves arranged opposite to each other and a positioning tube fixing clamp arranged between the two positioning tube fixing grooves. The shape of the bottom of the positioning tube fixing groove is adapted to the positioning tube. The positioning device fixing component includes two positioning device fixing grooves arranged opposite to each other and a positioning device fixing clamp arranged between the two positioning device fixing grooves. The shape of the bottom of the positioning device fixing groove matches the shape of the positioning device. The distance from the bottom of the positioning tube fixing groove to the fixing base plate is less than the distance from the bottom of the positioning device fixing groove to the fixing base plate. When the positioning tube and the positioning device are respectively fixed in the positioning tube fixing groove and the positioning device fixing groove, the central axes of the positioning tube and the positioning device in the horizontal direction are located on the same horizontal plane and parallel to the fixing base plate. The double-ear sleeve fixing platform fixes the positioning tube by fixing and supporting the double-ear sleeve.

[0008] In one embodiment, the double-ear sleeve fixing platform includes a second support base, a second fixing base plate fixed on the second support base, and a double-ear sleeve fixing member disposed on the second fixing base plate. The double-ear sleeve fixing member includes at least two sliding rod fixing plates and sliding rods with circular through holes. In use, the positioning tube is inserted into the double-ear sleeve, and the two ear holes of the double-ear sleeve are located between the two sliding rod fixing plates. The sliding rod passes through the circular through holes of the sliding rod fixing plates and the ear holes of the double-ear sleeve.

[0009] In one embodiment, both the positioning tube fixing groove and the positioning device fixing groove are groove plate structures.

[0010] In one embodiment, both the positioning tube fixing clamp and the positioning device fixing clamp include a base disposed on a fixed base plate, a clamp plate movably connected to the base, and a movable handle. The opening and closing angle of the clamp plate is controlled by the movable handle, which is used to fix the positioning tube and the positioning device from above.

[0011] In one embodiment, the fixed base plate 2 is provided with a fitting slot.

[0012] In one embodiment, the sliding rod is provided with a limiting pin, which is used to fix the sliding rod when it is limited to a certain position by the sliding rod fixing plate.

[0013] In one embodiment, the first support base and the second support base are trapezoidal, rectangular, square or I-shaped.

[0014] In one embodiment, the clamping plate and movable handle of the positioning tube fixing clamp and the positioning device fixing clamp form a 90° angle, and the opening and closing angle of the clamping plate can be controlled by the movable handle to fix the positioning tube and the positioning device.

[0015] In one embodiment, the positioning and fixing platform and the double-ear sleeve fixing platform are made of metal or alloy, which can improve the pressure resistance and stability of the device and extend its service life.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: the positioning fixing platform and the double-ear sleeve fixing platform are used in conjunction, the shape of the bottom of the positioning tube fixing groove is adapted to the positioning tube, and the shape of the bottom of the positioning device fixing groove is adapted to the positioning device. Because there is a thickness difference between the positioning tube and the positioning device, there is a height difference between the center lines of the positioning tube and the positioning device after they are laid flat. Therefore, the height difference between the bottom of the positioning tube fixing groove and the bottom of the positioning device fixing groove and the bottom of the positioning device fixing groove is designed to compensate for the thickness difference between the positioning tube and the positioning device, thereby promoting the positioning tube... When the positioning device is laid flat, its horizontal centerline is on the same horizontal plane and cannot move or deflect. This ensures that the centerlines of the positioning tube and the positioning device are on the same horizontal plane and will not loosen or slip during assembly. After the double-ear sleeve and positioning support are tightened, the positioning tube and the positioning device on the two fixed platforms are very stable. Subsequently, other related components of the positioning device can be installed with reference to this method. Because the operation is carried out on the ground, the installation difficulty of other related components is reduced, the installation standard is greatly improved, the operation is much less strenuous for the operator, and the operation time is also greatly reduced. Using this invention and operating method can improve work efficiency by at least 40%, and the first-time installation standard rate can be improved by at least 80%. This greatly reduces the probability of rework after the positioning device is installed on the contact line, significantly reduces the risk of equipment damage caused by non-standard installation of the positioning device, and effectively ensures the safe operation of the contact line.

Detailed Implementation

[0023] To facilitate understanding of this utility model, the following description will be provided in more comprehensive and detailed manner with reference to the accompanying drawings and preferred embodiments. However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0024] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by those skilled in the art. The technical terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the scope of protection of this invention.

[0025] Unless otherwise specified, all raw materials, reagents, instruments and equipment used in this invention can be purchased from the market or prepared by existing methods.

[0026] Please see Figure 1-4A portable pre-assembly platform for a high-speed rail contact network positioning device includes a positioning fixing platform 10 and a double-ear sleeve fixing platform 20 used in conjunction. The positioning fixing platform 10 is used to fix the positioning tube and the positioner, and includes a support base 130 and a fixing base plate 140 fixed on the support base 130, and positioning tube fixing components 110 and positioner fixing components 120 respectively disposed on the fixing base plate 140. The positioning tube fixing component 110 includes two positioning tube fixing grooves 112 disposed opposite to each other and a positioning tube fixing clamp 111 disposed between the two positioning tube fixing grooves 112. The positioner fixing component 120 includes two positioner fixing grooves 122 disposed opposite to each other and a positioner fixing clamp 121 disposed between the two positioner fixing grooves 122. The bottom of the positioning tube fixing groove 112 is arc-shaped, matching the cylindrical positioning tube. The bottom of the positioning device fixing groove 122 is rectangular, matching the rectangular positioning device. Because there is a thickness difference between the positioning tube and the positioning device, there is a height difference between the center lines of the positioning tube and the positioning device after they are laid flat. This height difference is designed as the standard height difference between the positioning tube fixing groove 112 and the positioning device fixing groove 122, so that the horizontal center lines of the positioning tube and the positioning device are in the same horizontal plane after they are laid flat. The double-ear sleeve fixing platform 20 includes a second support base 220, a second fixing base plate 230 fixed on the second support base 220, and a double-ear sleeve fixing component 210 disposed on the second fixing base plate 230. The double-ear sleeve fixing component 210 includes at least two sliding rod fixing plates 211 with circular openings in the middle, and a sliding rod 212 with a diameter matching the circular opening of the sliding rod fixing plate 211. In use, the positioning tube is inserted into the double-ear sleeve, and the two ear holes of the double-ear sleeve are located between the two sliding rod fixing plates 211. The sliding rod 212 passes through the circular through hole of the sliding rod fixing plate 211 and the ear hole of the double-ear sleeve, thereby fixing the other end of the positioning tube to the double-ear sleeve fixing platform 20. Preferably, the second fixing base plate 230 is provided with an accessory slot 215, which can hold small parts and tools such as original fitting pins, bolts, and cotter pins on the double-ear sleeve, making them easy to retrieve and less likely to be lost.

[0027] Preferably, the sliding rod 212 is provided with a limiting pin 213. The limiting pin 213 on the sliding rod 212 ensures that the sliding rod's pushing and pulling stroke reaches its intended use within the shortest distance and does not come loose during use. In one embodiment, when using the double-ear sleeve fixing platform 20 to fix the double-ear sleeve, the double-ear sleeve is placed between two sliding rod fixing plates. The sliding rod 212 is inserted through the ear holes of the double-ear sleeve from the other two sliding rod fixing plates 211, and fixed at a certain position by the limiting pin 213. Preferably, there are four sliding rod fixing plates 211, which can improve the stability of the sliding rod 212.

[0028] Specifically, in one embodiment, in order to reduce the overall weight of the device, preferably, the positioning tube fixing groove 112 is a split structure composed of two opposing positioning tube seat groove plates, and the positioning device fixing groove 122 is a split structure composed of two opposing positioning device seat groove plates. When fixing the positioning tube and the positioning device using the positioning fixing platform 10, the circular positioning tube and the rectangular positioning device are respectively placed flat into the two positioning tube fixing grooves 112 and the two positioning device fixing grooves 122. Both the positioning tube fixing clamp 111 and the positioning device fixing clamp 121 include a base set on the fixed base plate 140, a clamp plate movably connected to the base, and a movable handle. The movable handle and the clamp plate are connected by a hinge. The movable handle and the clamp plate are designed to form a 90° angle. The opening and closing angle of the clamp plate is controlled by the movable handle. The clamp plate adopts a press-fit design. In use, the clamp plate is opened and closed vertically by controlling the movable handle to fix the positioning tube and the positioning device from above. After locking and fixing, the height difference between the positioning tube fixing groove 112 and the positioning device fixing groove 122 compensates for the thickness difference between the positioning tube and the positioning device, keeping the center lines of the positioning device and the positioning tube on the same horizontal plane, parallel to the table surface of the supporting base 130, and unable to move or deflect.

[0029] Preferably, the positioning and fixing platform 10 and the double-ear sleeve fixing platform 20 are made of metal or alloy, which can improve the pressure resistance and stability of the device and extend its service life.

[0030] Preferably, the support bases 1 and 130 of the positioning fixing platform 10 and the double-ear sleeve fixing platform 20, and the support base 220 of the double-ear sleeve fixing platform 20, are all trapezoidal in design to increase stability.

[0031] Preferably, the sliding rod 212 adopts a metal cone-shaped design, which makes it easier to insert into the through hole of the double-ear sleeve. The diameter of the rod body matches the through hole of the double-ear sleeve, which can ensure that the double-ear sleeve will not loosen from side to side.

[0032] The working process of the portable pre-installation platform for the high-speed rail contact network positioning device is as follows: Based on the orientation of both ends of the positioning tube, place the double-ear sleeve fixing platform 20 at one end of the positioning tube, ensuring that the sliding rod 212 on the double-ear sleeve fixing platform is approximately perpendicular to the positioning tube, and confirm that the two sliding rod fixing plates 211 are not inserted. Then, place the positioning fixing platform 10 at the other end of the positioning tube, ensuring that the positioning tube fixing groove 112 on the positioning fixing platform 10 is approximately perpendicular to the positioning tube, and confirm that the locator fixing clamp 121 and the positioning tube fixing clamp 111 on the fixing platform are in the open state. Simultaneously, the positioning fixing platform 10 is equipped with a locator... One end of the fixing groove 122 is placed opposite the end of the double-ear sleeve fixing platform 20 which has the accessory groove 215 along the positioning tube. Then, the double-ear sleeve is placed in the double-ear sleeve groove. Make sure that the two tightening bolts on the double-ear sleeve are facing upwards and the opening of the double-ear sleeve is facing the positioning fixing platform 10. Then push the sliding rod 212 into the double ear hole of the double-ear sleeve. Push it until the limiting pin 213 of the sliding rod 212 is attached to the sliding rod fixing plate. Insert the positioning tube into the double-ear sleeve from the opening of the double-ear sleeve. The other end is placed on the positioning tube fixing groove 112 on the positioning fixing platform 10. Use a torque wrench to tighten the tightening bolts on the double-ear sleeve to the standard torque. Connect the locator to the locator support correctly. After connection, insert the locator support into the locator tube through the end near the locator tube fixing groove 112. After insertion, slide the locator support to the standard position. Then, place the locator into the locator fixing groove 122. Move the locator fixing platform 10 to the middle of the locator between the locator and the locator support. Lock the locator tube fixing clamp 111 and the locator fixing clamp 121 to ensure there is no looseness. The installation is now complete.

[0033] Based on the dimensional differences between the positioning tube and the positioning device of the high-speed railway contact network positioning system, a standard height difference is designed between the positioning device fixing groove 122 and the positioning tube fixing groove 112. Therefore, after locking, the center lines of the positioning tube and the positioning device will be controlled to be in the same horizontal plane. This causes the center axis of the positioning support sleeved on the positioning tube and the positioning device to be passively adjusted to be in the same horizontal plane as the center axis of the former two, and it cannot move or deflect. This ensures that the center axes of the positioning tube, the positioning device, and the positioning support are in the same horizontal plane, and they will not loosen or slip during assembly. Next, tighten the bolts on the positioning support according to the standard. After tightening the double-ear sleeve and positioning support, the positioning tube and positioning device on the two fixed platforms are very stable. Then, other related parts of the positioning device can be installed with reference. Since it is an overhead operation, the installation difficulty of other related parts is reduced and the installation standard is greatly improved. The operation is very labor-saving for the operator and the operation time is greatly reduced. After all the parts are pre-installed, open the positioning device fixing clamp 121 and the positioning tube fixing clamp 111, and pull out the sliding rod 212 from the double-ear sleeve. The entire positioning device can then be taken out.

[0034] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
