Description
Technical field
The utility model relates to a kind of Simple gantry crane.
Background technology
In the railway construction, while transforming especially AT STATION, usually need that the rail of having stacked is transferred to another position and stack.All to adopt man-handling of materials or crane transhipment now.
Reach heavily approximately 1500 kilograms of the P60 rail of 25 meters, if during transhipment by manpower, approximately need one of the transhipment in 20 minutes of people more than 20, and transport efficacy is lower, safety is less, needs the staff to assume unified command of good matching coordinative collaboration capabilities.Slightly have and do not notice that rail just can turn on one's side and fall, injure personnel by a crashing object.
If adopt the crane transhipment, need " car is crossed machine and stopped " owing to closing on both wired constructions, crane can not continuous firing, and camp site contacts electrical network in addition, and the putting of crane, sling height are had certain restriction.Reach in the rail lifting process of 25 meters safety hazard also more, need about ten people of cooperation personnel.And concentrate the rail of stacking to need bulk storage to arrive different positions, crane can't meet repeatedly hanging and turn of long distance.
Summary of the invention
The technical problems to be solved in the utility model: the problem for rail transhipment difficulty in present railway construction provides a kind of portable simplified gauntry crane that utilizes camp site material assembling.
The technical solution of the utility model:
A kind of portable simplified gauntry crane, comprise electric block, guide rail and two supports, and guide rail is rail, support is scaffold, the walking wheels of electric block are arranged on steel rail web, and cantilever tip is equipped with bottle gouard moved by hands, and the guide rail two ends are hung on support by bottle gouard moved by hands.
Two cross bars respectively are set below the guide rail two ends, cross bar is rack-mount and with fastener, guide rail and cross bar are fixed.
Be provided with the transfer support, its top is equipped with fixed pulley.
Be provided with the Simple gantry crane of two groups of parallel placements.
The beneficial effects of the utility model:
1. except electric block and bottle gouard moved by hands, the all material of this Simple gantry crane can obtain from camp site, what support adopted is the steel pipe scaffold overlap joint, assembling, convenient disassembly, light easy carrying, and highly can regulate arbitrarily, can meet the needs of different workyards, guide rail adopts existing rail, draw materials conveniently, do not need to carry at any time guide rail.
2. at first guide rail is moved to suitable position below support, then the traveling wheels are installed to above guide rail.After the hand pulling type chain and tackle block of rack-mount rises to certain altitude, two cross bars laterally are installed below support upper end, guide rail, after being placed, the pedestal of fixed guide falls guide rail, and go up clasp finally and make the guide rail can overturning.
3. the gauntry crane due to the design does not have the traveling function,, therefore can't shift voluntarily gauntry crane self, is designed for the transfer support that gauntry crane vertically moves, and first utilizes the transfer support temporarily to support guide rail, then gauntry crane is shifted.
4. be provided with the Simple gantry crane of two groups of parallel placements while carrying rail at every turn, lifting by crane respectively the two ends of rail to be transferred carries, transport an one steel rail to needing 5 people left and right, two minutes used times, portable freely-supported gauntry crane transfer tool rail is 10 times of man efficiency, is 6-12 times that wheel crane, loader draw the expense ratio.
Description of drawings:
Fig. 1 is the utility model schematic diagram.
The specific embodiment:
Embodiment: at first set up support 4, according to building operation fastener type steel pipe scaffold technical specification of security JGJ 130-2001, the fastener that the ductile castiron that fastener adopts material to meet " steel tube scaffold clasp " (GB 15831) regulation is made.Steel pipe adopts quality to meet the common steel tube of Q235-A level steel regulation in " structural carbon steel " (GB/T 700).It is of a size of Φ 48
3.5mm length is chosen according to actual needs.Be assemblied into 1
1
3m intersecting parallels framed structure, vertically be equipped with 1 at the right and left
The 4m square frame, install bottle gouard moved by hands 3 on support 4 tops, is used for lifting guide rail 2 and arrives certain height.On-site consolidation 4 pack supports 4, the center-to-center distance of vertical two pack supports 4 is the length of guide rail, the center-to-center distance of horizontal two pack supports is 15m.Then guide rail 2 is moved to the following suitable position of support 4, guide rail 2 is the P50 rail, then the traveling wheels of electric block 1 are installed on rail.The bottle gouard moved by hands 3 of guide rail two ends above being arranged on support 4 rises to certain altitude, and two cross bars 6 laterally are installed below support 4 upper ends, guide rail 2,, as the pedestal of fixed guide 2, falls guide rail 2, and upper clasp is fixed guide rail 2 and cross bar 6.Cross bar 6 is the 100mm*100mm channel-section steel.After two groups of simple and easy gantry support assembly units are completed, utilize two electric blocks 1 to lift by crane the two ends of rail to be transferred.
Electric block 1 finished product is bought by oneself, and the rail of required lifting mostly is the P60 tool track, and length is about 25 meters, about 1.5 tons of weight., according to the safe in operation standard, need adopt 25% safety factor during the cucurbit type selecting, 1.5
(1+25%)=1.875T, be the electric block of 2T therefore select specified lifting amount, and choosing maximum sling height according to the camp site situation is six meters.The wheels that its walking wheel is 2T by specified lifting amount form through improvement, and its wheel rim spacing is that 135mm(can regulate as required), can meet the needs of lifting, transhipment rail after being arranged on the guide rail beam web of the rail, the flange of rail.Bottle gouard moved by hands 3 is the chain and tackle block that pulls of 1T.
Bear and transmit various load actions for what make that fastener type steel pipe scaffold can be safe and reliable, its composition should meet following basic demand: 1, fastening bolt tighten torsional moment should be between 40N*m～60N*m, have enough rigidity and transmit the ability of load with the node that guarantees space frame structure.2, the ground of ricker must be solid with basis, should have enough load-carrying capacitys; Every bottom of upright rod should arrange base or backing plate.Backing plate should adopt length to be no less than two and be not less than the sheeting caps of 50mm across, thickness, also can adopt channel-section steel.Scaffold must arrange the vertical, horizontal bar of sweeping the floor, and the bar of vertically sweeping the floor should adopt right-angle coupler to be fixed on apart from the base epithelium and be not more than in the vertical rod at 200mm place.
3, longitudinal ligament (bridging) and cross-tie should be set,, so that scaffold has enough vertical and horizontal monolithic stability rigidity, perhaps with chain and tackle block, do vertical, transverse cable insurance.
Gauntry crane shifts: because the design's gauntry crane does not have the traveling function, therefore can't shift voluntarily gauntry crane self, therefore design processing is used for the transfer support that gauntry crane vertically moves, and this support adopts scaffold lapping to become intersecting parallels equally, and fixed pulley is installed in the above.Transfer process: (1) is installed to guide rail 2 midways location shifting support, and its fixed pulley is supported on guide rail 2 belows; (2) fastener at guide rail 2 two ends and bottle gouard moved by hands 3 are unclamped, guide rail 2 is vertically moved certain distance left; (3) support 4 on original the right is moved to the left end of guide rail, place and stablize, (4) move to the support 4 on the original left side right-hand member of guide rail, and the transfer support is taken in placement stable (5) finally away, adjusts gauntry crane and fixes each parts.
