Description

Line for Passenger Transportation CRTS I type track plate is taken off, the bed board device

Technical field

The utility model relates to a kind of track plate and takes off to mat formation and put.

Background technology

At present, the track plate is taken off, traditional method of bed board is to utilize remote fortune wooden handcart that the track plate is transported to the destination by the staff, is lifted by crane by crane again; The staff signals and accomplishes taking off, spreading of track plate, whole requirements of process cost great amount of time, and staff's work load is heavy; Energy consumption is big, and in addition, the use of main equipment has improved the needed cost of whole engineering; And can not guarantee the accuracy taking off, spread; Influence operating efficiency, and if large-scale crane can't construction section, engineering just is difficult to carry out.

Summary of the invention

The purpose of the utility model provides that a kind of Line for Passenger Transportation CRTS I type track plate is taken off, the bed board device, solve the technical problem that unpowered, low-cost, easy working track plate is taken off, spread.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

A kind of Line for Passenger Transportation CRTS I type track plate is taken off, the bed board device; Comprise the lifting frame; Said lifting frame comprises that two girders, two secondary beams, two foundation beams, four root posts and two assistants draw the cucurbit suspender, and the right ends portion of said two girders connects column respectively, and said two secondary beams are connected to the two ends of two girders; The bottom of two root posts is connected with the bottom girder with two secondary beam homonymies; Said two assistants draw the cucurbit suspender to be connected on the girder, and running gear comprises the four wheels that cooperates with track, and said wheel is connected below the column through wheel carrier.

Said column is isosceles triangle frame column or cube frame column.

A diagonal brace is each side arranged at the top of said column, and the other end of diagonal brace links to each other with girder, forms triangle between said girder, column and the diagonal brace.

The thickness of said wheel is less than the width of orbital groove.

Compared with prior art the utlity model has following characteristics and beneficial effect:

The utility model has overcome that the conventional rail guidance tape is taken off, the laying method cost is high, use the shortcoming of difficulty.

The utility model is a manual driven, does not need dynamical system, replaces traditional large-scale lifting appliance, has saved resource, has reduced cost.

Succinct dexterous, the easy accessibility of the utility model equipment is applicable to that large automobile crane can't construction section, can satisfy single line, curved section, heavy excavation highway section; The laying of track plate, take off plate; Accuracy also is superior to conventional method, therefore increases work efficiency, and the workload that reduces a staff.

The utility model can be widely used in the taking off of track plate, shop process.

Below in conjunction with accompanying drawing the utility model is done further detailed explanation.

Fig. 1 is the Lift-on/Lift-off System structural representation of the utility model.

Fig. 2 is the schematic side view of the utility model.

Fig. 3 is the running gear structural representation of the utility model.

Reference numeral: 1-girder, 2-secondary beam, 3-bottom girder, 4-column, 5-diagonal brace, 6-Chain block suspender, 7-wheel, 8-wheel carrier, 9-track.

The specific embodiment

Embodiment is referring to Fig. 1, shown in Figure 2, and a kind of Line for Passenger Transportation CRTS I type track plate is taken off, the bed board device, comprises the lifting frame; It is characterized in that: said lifting frame comprises that two girders 1, two secondary beams 2, two foundation beams 3, four root posts 4 and two assistants draw cucurbit suspender 6, and the right ends portion of said two girders 1 connects column 4 respectively, and said two secondary beams 2 are connected to the two ends of two girders 1; The bottom of two root posts 4 is connected with the bottom girder 3 with two secondary beam 2 homonymies; Said two assistants draw cucurbit suspender 6 to be connected on the girder, and a diagonal brace 5 is each side arranged at the top of said column 4, and the other end of diagonal brace 5 links to each other with girder 1; Form triangle between said girder 1, column 4 and the diagonal brace 3; The assurance structure stress is stable, and said column 4 is isosceles triangle frame column or cube frame column, when column 4 adopts isosceles triangle; Can add the weldering crossbeam in the middle part, to increase steadiness.

Running gear is referring to shown in Figure 3, and running gear comprises the four wheels 7 that cooperates with track 9, and said wheel 7 is connected below the column 4 through wheel carrier 8; Said track 9 is channel-section steels; The thickness of wheel 7 is less than the width of track 9 grooves, and driving force adopts artificial carrying out, and the part guarantees that with the crowbar crawl track Board position is accurate; Do not need power-driven system; With conventional method crane, signalman, slightly spread installation personnel, transport the required cost of wooden handcart relatively at a distance, reduced job costs, also alleviated staff's work load simultaneously.

The specified hoisting weight of present embodiment is 8t, and the traveling maximal rate is 5 kilometer per hours, and steering angle is 5 °; The rated load weight of Chain block suspender 6 is 3 tons; Power resources are that 4 people promote, the suspension bracket size long for 3.1m, wide be 3.2m, suspension centre apart from long be 2.5m, wide be 3.1m; Wheelspan long for 3.1m, wide be 3.2m, be suitable for one-sided, short distance is spread, take off the track plate.

Said Line for Passenger Transportation CRTS I type track plate is taken off, the method for using of bed board device, and step is following:

Step 1 before engineering is carried out, is laid track 9 in the needs construction road section in advance;

Step 2 places the device of the utility model on the track, and the hook of Chain block suspender 6 and the suspension ring of track plate are articulated;

Step 3 promotes Chain block suspender 6, the track plate sling;

Step 4, the device that promotes the utility model advances the appointed place of walking along track;

Step 5 with track plate let-down, is packed up Chain block suspender 6;

Completion is taken off, spread to step 6, repeating step two to step 5 up to this highway section track plate, pack up Chain block suspender 6 and track 9, prepare to carry out circulation next time.
