Abstract

The utility model discloses a drag plate device, which comprises a guide rail and a drag plate, wherein the guide rail is formed by two pieces of steel channel through back-to-back fixation and connection, steel channel legs of the steel channel form rails of the guide rail, the inner sides of the steel channel legs are provided with guide plate bodies, an abrasion-reducing plate is embedded in the upper end surface of the inner side of each guide plate body, the guide plate bodies are connected with the drag plate through combining screw bolts, the drag plate moves along the guide rail, rolling wheels are arranged in positions, corresponding to the rails, on the drag plate, and the rolling wheels roll on the upper end surface of the guide rail along the rails. In the operation process, the rolling wheels have flexibility and cannot be clamped in the rails, meanwhile, the abrasion of the rolling wheels on the rails is little, and the guide rail is effectively protected against abrasion; the occurrence of abrasion caused by direction contact between the guide plate bodies and the guide rail can be avoided through the abrasion-reducing plates embedded in the upper end surfaces of the inner sides of the guide plate bodies, after the operation for a long time, the abrasion on the abrasion-reducing plates per se is greater, in addition, the size of each abrasion-reducing plate is smaller, the cost is low, the replacement is convenient, and the maintenance cost is effectively reduced.

Description

A kind of carriage device

Technical field

The utility model relates to Down-hole rolling rig field, is specifically related to a kind of for the carriage device on Down-hole rolling rig.

Background technology

Used Down-hole rolling rig planker is arranged on guide rail, and guide plate body is installed in planker lower end, in the middle of planker and guide plate body, is provided with adjustment pad, and planker can move on guide rail, and the upper and lower two ends of guide rail rail level generally do not have safeguard measure.Planker is in operation, and guide rail rail level lower end directly contacts and produce friction with guide plate body upper surface, when planker gravity is supported in guide rail rail level upper end, forms and rubs with planker; Planker is on guide rail after long-term operation, and wear and tear because produced by friction in the upper and lower two ends of guide rail rail level, guide rail easily deforms, if the guide rail after distortion continues to use, planker is easily stuck on guide rail, thereby planker cannot normally be moved reposefully; Meanwhile, because guide rail build is large, be subject to site influence, the guide rail after wearing and tearing is changed inconvenience, maintenance cost is high.

Utility model content

The purpose of this utility model is to provide a kind of flexible operation and the carriage device steady, abrasion resistance is strong, maintenance cost is low.

To achieve these goals, the technical solution adopted in the utility model is as follows:

A kind of carriage device, comprise guide rail and planker, guide rail is formed by fixedly connecting dorsad by two channel-section steels, the channel-section steel leg of channel-section steel forms the track of guide rail, and channel-section steel inboard leg is provided with guide plate body, and guide plate body inner top side face is embedded with wearing plate, guide plate body is connected with planker by assembling bolt, planker moves along guide rail, on planker, is provided with roller with track corresponding position, and roller rolls in guide rail upper surface along track.

Preferably, guide plate body is four.

Preferably, roller is four.

The beneficial effects of the utility model are: when planker moves on guide rail, the roller being arranged on planker rolls in guide rail upper surface along track, and roller has flexibility, can not block in orbit; Meanwhile, the abrasion of pair of rollers track is few, has effectively protected guide rail not frayed; Guide plate body inner top side face is embedded with wearing plate, and wearing plate avoids guide plate body directly to contact with guide rail, in service for a long time, only have wearing plate friction impaired, and wearing plate build is less, and wearing plate cost low, be convenient to change, effectively reduce maintenance cost.

Detailed description of the invention

In order further to understand the utility model, below in conjunction with embodiment, the utility model preferred embodiment is described, but should be appreciated that these describe just in order to further illustrate feature and advantage of the present utility model, instead of restriction to the utility model claim.

Below in conjunction with the accompanying drawing in the utility model embodiment, the scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the embodiment of the utility model part, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1 to Figure 3, the utility model embodiment provides a kind of carriage device, this carriage device comprises guide rail 1 and planker 2, wherein: guide rail 1 is formed by fixedly connecting dorsad by two channel-section steels, steel plate 10 is for being fixedly connected with two channel-section steels, the channel-section steel leg 9 of channel-section steel 6 forms the track 11 of guide rail 1, channel-section steel leg 9 inner sides are provided with guide plate body 3, guide plate body 3 inner top side faces are embedded with wearing plate 4, guide plate body 3 is connected with planker 2 by assembling bolt 8, planker 2 moves along guide rail 1, on planker 2, be provided with roller 5 with track 11 corresponding positions, roller 5 rolls on guide rail 1 along track 11 upper surfaces.

In the utility model embodiment, as shown in Figure 2, guide plate body is four, four guide plate bodies lay respectively at the below, tetra-regions of A, B, C, D of planker 2, the guide plate body in each region is connected with planker 2 by three assembling bolts 8, the guide plate body inner top side face in each region is embedded with wearing plate, and wearing plate protection track 11 lower surfaces are not rubbed; Planker is on guide rail after long-term operation, and wearing plate itself is worn larger, and track 11 lower surfaces are not frayed, and wearing plate build is less, cost is low, be convenient to replacing, has effectively reduced maintenance cost.
