Problems solved by technology

At present, the driving equipment for outdoor operations is relatively mature, but due to the characteristics of engineering construction, various equipment is relatively heavy and noisy, and is not suitable for small spaces or indoor operations such as laying concrete, leveling the ground, pressing, etc.
[0003] In the traditional building concrete floor construction, manual leveling is often used, and the levelness of the floor by manual operation is difficult to meet the requirements, and the construction efficiency is low
In the existing small floor machines, the vertical angle of the leveling head and the horizontal adjustment of the troweling plate are adjusted by the push and pull force of the oil cylinder. During the construction, due to the change of the working conditions, the machine body of the floor machine will suddenly tilt longitudinally, which will cause It causes the longitudinal tilt of the leveling head and the tilt of the laser receiver. When the leveling head is tilted longitudinally, it causes the change of the laser signal reception and the recalculation error. The calibration information of the receiver is transmitted to the controller, and then the controller instructs the actuator to adjust the leveling head. The change of horizontal plane and longitudinal inclination makes the program control complicated and time-consuming. Secondly, the existing equipment adopts electro-hydraulic control. The travel transmission system and the cylinder push-pull execution system are all driven by the hydraulic system. The existing equipment adopts the coordinated control of the two systems The reaction speed and execution control of this method are slow, and the unevenness of the concrete surface is poor in quality, and the maintenance cost and purchase cost are high. Secondly, because the engine is used as the power source, it is not conducive to environmental protection, especially in the indoor space of buildings. The exhaust gas emitted by the engine will cause pollution. Cause personal injury, large-scale equipment floor machine can not work due to the limitation of indoor space in the indoor construction of the building

Embodiment 1

[0027] A small engineering vehicle drive main engine, including a casing 51, two hangers 54 inclined upwards for mounting attachments are fixed in front of the casing 51, and at least a pair of driving The wheel 52, the driving wheel 52 and the casing 51 are fixedly connected or connected with an adjustable center of gravity of the main engine.

[0028] The above-mentioned small engineering vehicle drives the main engine, the drive wheel 52 and the casing 51 are adjustable, and the casing 51 is provided with a lead screw 61, and one end of the lead screw 61 is screwed and matched with the wheel frame 521, The other end is provided with a handwheel 6; the wheel frame 521 is provided with several elongated holes and connected with the casing 51 through bolts, and the driving wheels 52 are arranged on the left and right sides of the wheel frame 521. When adjustment is required, first loosen the bolts, then turn the hand wheel to adjust the body of the main unit to a suitable posi...

Embodiment 2

[0035] The main engine is driven by the small engineering vehicle in this embodiment, and the rear wheels 58 are foldable.

[0036] The rear wheel 58 is hinged to the casing 51 and a positioning pin is provided at the hinge to fix the position of the rear wheel 58 . Rear wheel 57 can be selected caster for use, and rear wheel 57 can be convenient to main engine to turn to after folding, and can play a supporting role when put down. The handle 56 can be cut into a certain shape with a plate, and the hand contact part is made into two semi-arc shapes with plastic or wooden materials and fixed on both sides of the plate to form an arc shape.

Abstract

The invention provides a small engineering vehicle driving main engine which comprises a shell. Two hanging brackets which are arranged obliquely upwards and used for mounting accessories are fixedlyarranged in front of the shell. At least one pair of driving wheels are arranged at the bottom of the shell. The driving wheels and the shell are fixedly connected or are connected in a main engine gravity center adjustable mode. The small engineering vehicle driving main engine is compact in structure and small in occupation space, and the accessories are convenient to assemble and drive.

Description

technical field [0001] The invention relates to a vehicle for engineering construction, in particular to a small-scale engineering vehicle driving a main engine and a floor machine suitable for indoor operations. Background technique [0002] Many construction equipment in construction, highway construction and other engineering industries drive corresponding attachments or molds through a host. At present, the driving equipment for outdoor work is relatively mature, but precisely because of the characteristics of engineering construction, various equipment is relatively bulky and noisy, and is not suitable for small spaces or indoor operations such as laying concrete, leveling the ground, and pressing. [0003] In the traditional building concrete floor construction, manual leveling is often used, and it is difficult to meet the requirements for floor flatness by manual operation, and the construction efficiency is low. In the existing small floor machines, the vertical an...
