Summary of the invention
The present invention is in order to solve the conventional concrete vibrating mode in the big position of existing prefabricated bridge reinforcement consumption, and degree of compactness is not enough, causes the problem of the defect such as hollowing, cavity, it provides a kind of adsorption type precast bridge bed die vibration chassis.
The present invention adopts following technical scheme to realize:
A kind of adsorption type precast bridge bed die vibration chassis, comprises running gear, adsorption unit and vibrating device,
Described running gear comprises dolly, the headroom that the vehicle body width of dolly and total height are less than under beam making bench buttress, vehicle body length is the length that beam-ends one saves template, dolly comprises vehicle frame, vehicle frame is that the three-layer stereo framework being made up of longeron, crossbeam and column, the spacing of adjacent beams and the spacing of adjacent upright posts are identical with the spacing of bed die crossbeam adjacent under bridge bed die;
Described adsorption unit is magneticchuck, and magneticchuck is fixed on the superiors of vehicle frame, corresponding to position in the middle of each bed die crossbeam; Magneticchuck will produce powerful adsorptive power after switching on power.
Described vibrating device is arranged on middle one layer of vehicle frame, comprise motor, transmission shaft, axle bed and eccentric block, axle bed is arranged in the middle of each crossbeam of vehicle frame, propeller shaft length is that vehicle body is elongated, is arranged on vehicle frame by axle bed, and transmission shaft is equipped with some eccentric blocks, each eccentric block is uniformly distributed on axle, longitudinally being arranged in the middle of adjacent two crossbeams of vehicle frame respectively, motor is installed on frame end, and motor and transmission shaft are connected by junctor; After motor switches on power, drive transmission shaft and eccentric block are produced powerful vibration power.
Being provided with position block on dolly, described position block is the steelframe being welded in vehicle frame orlop, and the spacing between position block and vehicle frame first crossbeam is equal to the spacing of beam-ends mould to bridge bed die first bed die crossbeam. Position block can ensure that dolly accurately puts in place.
Hinge structure of the present invention has following useful effect:
1, novel, the pioneering feature utilizing precast bridge bed die to make for steel, adopts electromagnetic adsorption mode to arrange vibrating device under bed die, solves the vibration problem to bed die.
2, compact construction, connection and reasonable arrangement, together with being combined in adsorption unit, vibrating device with running gear, it is achieved that the function of expection ingeniously.
3, chassis convenience quick for installation, transfer flexibly, can have enough to meet the need use. After bridge concrete builds use on a pedestal, the other end or another pedestal can be transferred at once. Therefore equipment investment is greatly reduced, it is to increase working efficiency.
4, chassis can be precast bridge concrete provides powerful bed die to vibrate, and effectively improves beam body concrete particularly concrete vibrating quality bottom beam-ends, overcomes support plate place concrete hollowing phenomenon.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is I-I sectional view of Fig. 1;
In figure: 1-bridge bed die, 2-bed die crossbeam, 3-magneticchuck, the eccentric block of 4-, 5-transmission shaft, 6-motor, 7-position block, 8-wheel, 9-handle, 10-vehicle frame, 11-axle bed.
Embodiment
By reference to the accompanying drawings the specific embodiment of the present invention is described further.
One, chassis structure
Chassis is by running gear, adsorption unit and vibrating device three part composition. See accompanying drawing 1,2.
1, running gear
Running gear is one four and takes turns dolly, and vehicle body frame body is the three layers of space frame adopting shaped steel to be welded, and forms three-layer stereo framework by longeron, crossbeam and column, and crossbeam is identical with the gooseneck spacing under beam bed die with column spacing. The headroom that vehicle body width and total height are less than under beam making bench buttress. Vehicle body length is the length that beam-ends one saves template. The suitable position of vehicle body is provided with cart handle 9 and position block 7, for promoting carriage walking and located by dolly. Position block 7 is a steelframe, is welded on lower floor's vehicle frame, and the spacing between itself and vehicle frame first crossbeam is equal to the spacing of beam-ends mould to beam bed die first crossbeam.
2, adsorption unit
Adsorption unit is magneticchuck 3. It is fixed in the middle of every root crossbeam of vehicle frame 10 the superiors. Sucker spacing is identical with the spacing of bed die crossbeam 2 adjacent under bridge bed die. When dolly is in place, magneticchuck is just just positioned at below bed die crossbeam 2, once energising, magneticchuck 3 just just produces powerful adsorptive power, is adsorbed on bed die crossbeam 2 firmly, the vibration power of vibrating device is passed to bed die.
3, vibrating device
Vibrating device is arranged on middle one layer of vehicle frame 10, is made up of motor 6, transmission shaft 5, axle bed 11 and eccentric block 5. Axle bed 11 is arranged in the middle of each crossbeam. Transmission shaft 5 length is that vehicle body is elongated, is arranged on frame cross by axle bed. Some eccentric blocks 4 are housed on transmission shaft 5, and eccentric block 4 is uniformly distributed on axle, and longitudinal position is in the middle of two adjacent beams. Motor 6 is installed on vehicle body end. Motor 6 and transmission shaft 5 are connected by junctor. During work, motor 6 drives transmission shaft 5 and the eccentric block 4 on it to rotate, and provides vibration power to bed die.
Two, chassis uses
1, before beam body concrete is built, chassis being pushed into beam-ends, alignment bridge bed die 1 time neutral gear advances vehicle body below bridge bed die 1. Being attached on beam-ends mould to position block 7, now magneticchuck just aligns bed die crossbeam 2.
2, connect the power supply of magneticchuck 3, chassis is adsorbed on bed die crossbeam 2.
3, when building this section concrete, connect vibrating device power supply, concrete is vibrated.
4, after this section concrete has been built, stopping vibrating, disconnect magneticchuck 3 power supply, pull-out chassis, the other end or another pedestal that are transferred to beam use.
