Abstract

A traveling mechanism of a single-axle type bridge detection and maintenance vehicle is arranged on the lower portion of a vehicle body. The traveling mechanism is composed of a pulling rope 9, a hand-cranking disc 8, a spindle 7, a driving bevel gear 6, a driven bevel gear 5, a driven shaft 3 and the like. The spindle 7 is installed on the lower portion of the vehicle body 1 in the moving direction of the complete vehicle body 1 through a spindle base 10, the driven shaft 3 is perpendicular to the moving direction of the vehicle body 1 and installed on the lower portion of the vehicle body 1 through a driven shaft base 4 and a driven shaft base 2, and the pulling rope 9 is arranged between the driven shaft base 4 and the driven shaft base 2 of the driven shaft 3. The traveling mechanism is reasonable in design and simple in structure. The single-axle type bridge detection and maintenance vehicle with the mechanism is convenient to use, reliable, low in cost, and free of electric equipment and power generation equipment.

Description

A kind of single bridge-type bridge detects, the walking mechanism of maintenance cart

Technical field

The utility model belongs to bridge technology field, specifically the walking mechanism of a kind of single bridge-type bridge detection, maintenance cart.

Background technology

Bridge detects, maintenance cart is that one can detect for bridge, attendant provides job platform in detection, maintenance process, is equipped with bridge detecting instrument device, for the special purpose vehicle of flow detection and (or) maintenance activity.It is shift position at any time, can allow testing staff enter job position safe, fast, efficiently and carry out flow detection or maintenance activity, do not affect traffic when work.Bridge inspection vehicle is mainly two kinds at present, one is to use automobile as parent, on automobile, configure hanging basket or folding arm, automobile is delivered to testing staff under bridge and is detected and upkeep operation by hanging basket or folding arm at bridge floor, this car is not fixed, and can detect different bridges, upkeep operation.Its operating principle be all by hydraulic system by working arm bending be deep at the bottom of bridge to bridge detect, upkeep operation.Its problem is expensive, is not that a lot of units is difficult to bear to bridge Detection task, and the overwhelming majority bear to bridge detect, the unit task of maintenance task is not a lot.Another kind is single bridge-type bridge inspection vehicle, and this inspection vehicle is installed in bridge floor bottom, can move along the current direction of bridge floor automobile, and only to having installed, the bridge bottom of this car is detected, upkeep operation, and price is more cheap comparatively speaking.Its problem is that this bridge inspection vehicle is hung under bridge along prior default rail moving, because ordinary circumstance does not all have power supply, there is power supply also due to the long bad wiring of displacement, all to use the generating equipment carrying to realize the movement of inspection vehicle, because the moving track span of inspection vehicle is far away, inspection vehicle moves two motors of driving wheel and drives respectively, is difficult to synchronous, and each detect, safeguard and all need to be with generator, fuel oil, very inconvenient.

Summary of the invention

The purpose of this utility model is just to provide that a kind of a kind of single bridge-type bridge that can overcome the above-mentioned deficiency of existing single bridge-type bridge inspection vehicle detects, the walking mechanism of maintenance cart.

For achieving the above object, the utility model has been taked following technical scheme: a kind of single bridge-type bridge detects, the walking mechanism of maintenance cart, be installed in the bottom of car body, formed by pull rope 9, hand dish 8, main shaft 7, spindle drum 10, drive bevel gear 6, driven wheel of differential 5, driven axle bed 4, driven shaft 3 and driven axle bed 2; Main shaft 7 is installed on car body 1 bottom along car body 1 moving direction by spindle drum 10, and its left end is fixed with hand dish 8, and left end is fixed with drive bevel gear 6; Driven shaft 3 is installed on car body 1 bottom perpendicular to car body 1 moving direction by driven axle bed 4, driven axle bed 2, its front end is provided with the driven wheel of differential 5 engaging with drive bevel gear 6, installing pull rope 9 in position between its driven axle bed 4 and driven axle bed 2, pull rope 9 is around driven shaft 3 a few rear tensionings, and two ends are individually fixed in bridge pier proper site; Pull rope 9 is non-slip when ensureing that driven shaft 3 rotates, and it is polyhedron shape that driven shaft 3 is designed to cross section at the position of driven

axle bed

4,2 winding pull ropes 9 of driven axle bed.

Owing to having adopted technique scheme, the utility model has perfectly been realized its goal of the invention, and its single bridge-type bridge reasonable in design, simple in structure, that use this mechanism detects, maintenance cart is easy to use, reliable, and adult is low, does not need electricity consumption and generating equipment.

Brief description of the drawings

Accompanying drawing is concrete structure schematic diagram of the present utility model.

Detailed description of the invention

A kind of single bridge-type bridge the utility model being provided below in conjunction with accompanying drawing detects, the walking mechanism of maintenance cart is described in further detail: the walking mechanism of a kind of single bridge-type bridge detection, maintenance cart as shown in drawings, be installed in the bottom of car body, formed by pull rope 9, hand dish 8, main shaft 7, spindle drum 10, drive bevel gear 6, driven wheel of differential 5, driven axle bed 4, driven shaft 3 and driven axle bed 2; Main shaft 7 is installed on car body 1 bottom along car body 1 moving direction by spindle drum 10, and its left end is fixed with hand dish 8, and left end is fixed with drive bevel gear 6; Driven shaft 3 is installed on car body 1 bottom perpendicular to car body 1 moving direction by driven axle bed 4, driven axle bed 2, its front end is provided with the driven wheel of differential 5 engaging with drive bevel gear 6, installing pull rope 9 in position between its driven axle bed 4 and driven axle bed 2, pull rope 9 is around driven shaft 3 a few rear tensionings, and two ends are individually fixed in bridge pier proper site; Pull rope 9 is non-slip when ensureing that driven shaft 3 rotates, and it is polyhedron shape that driven shaft 3 is designed to cross section at the position of driven

axle bed

4,2 winding pull ropes 9 of driven axle bed.It can be also worm type of reduction gearing that the transmission that drive bevel gear 6 of the present utility model, driven wheel of differential 5 form is paid.

Operating principle and the process of utility model are as follows: rotate hand dish 8 with hand clockwise direction, hand dish 8 rotates and drives the main shaft 7 connecting firmly with it to rotate, main shaft 7 rotates and drives drive bevel gear 6 to rotate, drive bevel gear 6 main shafts 7 rotate and drive driven wheel of differential 5 to rotate, driven wheel of differential 5 rotates and drives driven shafts 3 to rotate, and driven shaft 3 rotates that loosen on pull rope 9 left sides that make to be wound around thereon, the right turns tightly, thus car load 1 parallel to the right, otherwise, car load 1 parallel left.
