Description

TECHNICAL FIELD

[0001] The utility model relates to the field of catenary simplified wrist arm production, concretely relates to a simplified wrist arm pre-arrangement platform. BACKGROUND

[0002] With the rapid development of railway construction, new requirements are put forward for the process quality standards of related parts in the railway industry, and the construction and maintenance precision of the driving line are increasingly required. In the driving line of the railway, the catenary is an important part of ensuring the normal operation of the railway, which is lapped on the power supply line of the electric railway and directly undertakes the primary task of energy supply for electric trains. The wrist arm is a catenary support device, and the wrist arm pre-arrangement is an important content in the construction of electrified railways. High-speed railways have very high precision requirements for the installation of catenaries, and most of the parts of high-speed railway catenary projects cannot be repeatedly disassembled. After accurate calculation, the wrist arm support device must be accurately assembled in place at one time. Due to the constraints of high-altitude conditions and other conditions, it is necessary to adopt the mode of pre-arrangement on the ground in batches. The quality, progress and construction efficiency of the subsequent construction are directly affected by the one-time construction of the entire catenary suspension. The simplified wrist arm includes an inclined wrist arm and a flat wrist arm. The assembly of the inclined wrist arm requires installing a support connector, a combined positioning ring, an inclined positioning column, a support connector, and a combined positioning ring on the wrist arm pipe in sequence. The assembly of the flat wrist arm requires installing a support connector, a combined positioning ring, a wrist arm connector, a support connector, and a combined positioning ring on the wrist arm pipe in sequence. These fittings that need to be installed on the wrist arm pipe have requirements for installation position and precision. In the traditional assembly of the inclined wrist arm and the flat wrist arm, the position interval is measured manually before assembly, which is inconvenient to operate and has insufficient assembly precision, thereby reducing the pass rate of finished products.

[0003] Therefore, the utility model provides a simplified wrist arm pre-arrangement platform, which realizes one-time positioning of the fittings that need to be assembled on the wrist arm pipe, is more convenient to assemble, ensures assembly precision, and improves the pass rate of finished products.

Figure 1 Install the components in the order and direction shown on the assembly support 11 located at the rear of platform 1, and adjust the spacing between them according to the design requirements. Then, install the support connector 41, the combination positioning ring 61, and the carousel connector on the single bolt single pin installation assembly 4, the double bolt single pin installation assembly 6, and the double bolt double pin installation assembly 7, respectively. Then, place the flat carousel tube 21 on the flat carousel fixing assembly 3, the support connector 41, the combination positioning ring 61, the carousel connector, the combination positioning ring 61, and the single bolt single pin installation assembly 4, and align the left end of the flat carousel tube 21 with the flat carousel fixing assembly 3 as required. Then, tighten and fix the support connector 41, the combination positioning ring 61, the carousel connector, the combination positioning ring 61, and the single bolt single pin installation assembly 4 to complete the assembly of the flat carousel.

The plate head 911 includes a head plate and an ear ring. The ear ring and the head plate are detachably connected. When the inclined column 91 is pre-installed on the inclined column mounting assembly 9, the plate head of the inclined column 91 is placed on the inclined column mounting platform 921, and the two ends of the head plate are pressed against the inner side of the inclined column locators 93 on both sides to adjust the inclined column 91 to a suitable position. At the same time, the column part 91 is placed in the support groove 941 at the upper end of the inclined column support block 94. Then, the inclined column positioning pin head 951 is pressed against the upper end of the column part 912 by pressing down the inclined column quick clamp 95, thereby fixing the position of the column part 912. At this point, the ear loop and the headplate are not fully tightened and fixed so that the arm tube can pass through the side of the ear loop. After the position of the arm tube is adjusted, the ear loop and the headplate are tightened and fixed to fix the position of the inclined column 91 and the arm tube.
