Description

Technical Field

[0001] The utility model relates to the field of installation of traveling crane current collectors, in particular to an installation rack for a traveling crane current collector. Background Art

[0002] A traveling crane current collector, also known as a sliding contact line current collector or a current collector, is a device used for traveling cranes and other mobile devices to collect electric power from a fixed conductive track. This device is very common in industrial production, especially on large machinery that needs to move over a long distance. The main function of the traveling crane current collector is to ensure that the mobile device can obtain electric power stably and safely to support its operation.

[0003] Currently, in the fertilizer ripening warehouse, due to the harsh environment, acidic gases and dust corrode the traveling crane all year round, resulting in a relatively high failure rate of the traveling crane. In particular, the failures caused by the incoming wire rail, current collector support and current collector cutter head of the traveling crane account for more than 85% of the total failure rate. Among them, replacing the current collector support and the current collector cutter head is the most common maintenance method. However, due to defects in the current collector and the installation support structure in the design of the traveling crane, the maintenance is very difficult. The main defects include: since the installation position of the traveling crane current collector is close to the traveling crane, when the maintenance personnel stand outside to disassemble the outer current collector, they need to stretch out half of their body into the traveling crane, and due to the long disassembly time, it causes a large physical consumption. In addition, when disassembling the current collector, it is very difficult to operate the wrench and the hand. Especially when disassembling the inner current collector, it is often necessary to first remove the outer current collector, which increases the maintenance difficulty and time. Therefore, an installation rack for a traveling crane current collector is proposed to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] As Figures 1-3 shown, an installation rack for a traveling collector includes a vertical hanging part 1, a horizontal support frame 2 and a relay installation rack 3. Among them, the top of the vertical hanging part 1 is connected to the traveling crane, and the specific connection method can adopt welding or bolt connection. The horizontal support frame 2 is arranged at the bottom of the vertical hanging part 1 and is perpendicular to the vertical hanging part 1. The relay installation rack 3 includes a transverse moving support frame 30 slidably arranged at the front end of the horizontal support frame 2. The top of the transverse moving support frame 30 is provided with a lifting support frame 31 that can be lifted and lowered, and the lifting support frame 31 is used for installing the traveling collector.

[0026] With such a design, when the overhead collector needs to be repaired, the overhead collector can be appropriately lowered by the lifting support frame 31 first to disengage it from the conductive rail, and then the entire collector system can be moved outside the overhead crane by the lateral sliding of the lateral movement support frame 30 on the horizontal support frame 2, which facilitates the repair of the collector, improves the convenience of repair. At the same time, when removing the inner collector, it is not necessary to remove the outer collector first, which greatly improves the repair efficiency.

[0027] In the preferred embodiment, the horizontal support frame 2 includes two symmetrically arranged support sliding rods 202. A gap is reserved between the two support sliding rods 202 for facilitating the disassembly and assembly of the overhead collector. Through the gap, the distance between the two collectors on both sides can be effectively enlarged, so as to facilitate the disassembly and assembly of the bolts on the opposite sides of the two collectors. The lateral movement support frame 30 is slidably arranged at the front ends of the two support sliding rods 2.

[0028] Furthermore, in order to improve the installation stability of the support sliding rods 202, the horizontal support frame 2 further includes a support cross beam 201 arranged on the back of the vertical lifting part 1. In this embodiment, both the support cross beam 201 and the vertical lifting part 1 are concave channel steels, and the bottom plates of the two are attached to each other and fixed by welding or bolt connection. The ends of the two support sliding rods 202 pass through the two sides of the vertical lifting part 1 and are respectively installed on the support cross beam 201 through U-shaped pipe clamps 205. The U-shaped pipe clamps 205 are also fixed by welding or bolt connection. Two connecting cross rods 203 connecting the two are welded between the two support sliding rods 202. One of them is located at the front ends of the two support sliding rods 202, and the other is close to the vertical lifting part 1 and cooperates with the vertical lifting part 1 to clamp the vertical lifting part 1 therein. The lateral movement support frame 30 can slide on the support sliding rods 202 between the two connecting cross rods 203. An inclined strut 204 is also welded between the support cross beam 201 and the support sliding rods 202. Through the above structure, a stable and effective support structure can be formed.

[0029] In the preferred embodiment, the lateral movement support frame 30 includes two sliding sleeves 301 respectively slidably sleeved on the two support sliding rods 2, and locking components for locking their positions are arranged on the outer sides of the two sliding sleeves 301. A first connecting frame 304 is arranged between the two sliding sleeves 301. Through the sliding of the sliding sleeves 301 on the support sliding rods 2, the effect of lateral movement is achieved.

[0030] Among them, the locking component includes a first threaded sleeve 302 arranged on the outer side of the sliding sleeve 301 and communicating with its interior. A locking bolt 303 is threadedly installed in the first threaded sleeve 302. The position of the lateral movement support frame 30 is locked by tightening and loosening the locking bolt 303.

[0031] It should be noted that the number of locking components on each sliding sleeve 301 can be adjusted as needed. In this embodiment, the number of locking components on each sliding sleeve 301 is two.

[0032] In a preferred solution, a locking groove 206 matching the locking bolt 303 is arranged on the outer side of the support sliding rod 202. The length of the locking groove 206 matches the sliding distance of the transverse moving support frame 30. Through the locking groove 206, the moving length of the locking bolt 303 can be effectively increased, and at the same time, the contact area at the end of the locking bolt 303 is enlarged, which can effectively improve the locking effect.

[0033] In addition, a rubber pad is arranged at the end of the locking bolt 303, which can further improve the locking effect.

[0034] In a preferred solution, the lifting support frame 31 includes two symmetrically arranged square tubes 310, which are respectively used to install the traveling current collectors on both sides. A second connecting frame 311 for connecting the two is welded between the two square tubes 310. Perforations 308 are arranged at the four corners of the first connecting frame 304. A lifting limiting rod 312 opposite to the perforation 308 is welded at the bottom of the second connecting frame 311. The bottom end of the lifting limiting rod 312 passes through the perforation 308 and is welded with a limiting plate 313. A jacking component for controlling the lifting of the lifting support frame 31 is also arranged on the first connecting frame 304.

[0035] With such a design, the lifting support frame 31 can be stably lifted and lowered on the transverse moving support frame 30 through the telescopic movement of the lifting limiting rod 312 in the perforation 308. At the same time, the limiting plate 313 can play the role of limiting the lifting height of the lifting support frame 31 and can also play the role of positioning the height.

[0036] The jacking component includes a main jacking part penetrating through the center of the first connecting frame 304, which includes a second threaded sleeve 305 welded through the center of the first connecting frame 304. A jacking screw 306 with its top end in contact with the bottom of the second connecting frame 311 is threadedly installed in the second threaded sleeve 305. A hand-operated turntable 307 is arranged at the bottom end of the jacking screw 306.

[0037] During use, the rotation of the jacking screw 306 in the second threaded sleeve 305 can be controlled through the hand-operated turntable 307, so as to realize the effect of jacking the lifting support frame 31 to rise and fall.

[0038] In a preferred solution, the jacking component includes a plurality of auxiliary jacking parts arranged on both sides of the main jacking part, and their structures are the same as that of the main jacking part. In this embodiment, the number of the auxiliary jacking parts is two, which are respectively located on both sides of the main jacking part. The stability of the support for the lifting support frame 31 can be effectively improved through the auxiliary jacking parts.

[0039] It should be noted that when the lifting support frame 31 is lifted, the main pushing part is adjusted first, and when the lifting support frame 31 is lowered, the main pushing part is adjusted last.

[0040] In this embodiment, both the second connecting frame 311 and the first connecting frame 304 are I-shaped connecting frames, and both the main pushing part and the auxiliary pushing part are arranged on the connecting beam in the middle of the I-shaped connecting frame.

[0041] In addition, in order to reduce the overall weight of the device, both the horizontal support frame 2 and the relay mounting frame 3 adopt a hollow steel pipe structure.

[0042] In a preferred solution, in order to reduce the friction force of the pushing screw 306 of the main pushing part against the lifting support frame 31 during rotation, a rotating table 32 is provided at the bottom of the second connecting frame 311, which corresponds to the top end of the pushing screw 306 of the main pushing part. Specifically, it includes a rotating seat 320 provided at the bottom of the second connecting frame 311. The rotating seat 320 can be fixed to the bottom of the second connecting frame 311 by welding or screw mounting. A T-shaped cavity 321 is provided in the rotating seat 320, and a T-shaped rotating shaft 322 is rotatably provided in the T-shaped cavity 321. Through the shape fit between the T-shaped cavity 321 and the T-shaped rotating shaft 322, the T-shaped rotating shaft 322 can be hoisted therein. The bottom end of the T-shaped rotating shaft 322 passes through the T-shaped cavity 321 and is connected with a contact seat 324. Rollable balls 323 are provided on both the top and the side wall of the T-shaped rotating shaft 322, and the balls 323 are in contact with the corresponding wall of the T-shaped cavity 321.

[0043] With such a design, the pushing screw 306 of the main pushing part can be in contact with the bottom of the contact seat 324. When the pushing screw 306 rotates, the rotation of the T-shaped rotating shaft 322 in the T-shaped cavity 321 can reduce the friction force between the second connecting frame 311. In this embodiment, the contact seat 324 is an inverted concave shape, and its groove is adapted to the diameter of the pushing screw 306.

[0044] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
