technical field

The invention relates to the field of side wall construction, in particular to a formwork trolley for a single side wall.

Background technique

When building tunnels such as tunnels, culverts, subways, etc., side walls are often required to be built. Due to the thicker thickness of the side walls, they are generally constructed by pouring. As shown in Figure 1, when pouring the side wall, first use the template and the soil wall in the tunnel or the wall built in advance to form the mold cavity. During the construction process, the mold is first erected, the template is erected, and then supported by the support frame Formwork, the support frame is composed of vertical rods, horizontal bottom rods and inclined rods. The back of the formwork is connected to the vertical rods through hook bolts, and the bottom of the support frame is connected to the tie bars embedded in the soil to ensure the construction of the bottom frame. stability in the process.

In the process of vertical formwork, the formwork needs to be manually installed and adjusted, and the artificial fatigue strength is high, and after the pouring is completed, the demoulding operation needs to be carried out to remove the formwork; when the existing formwork is demolded, the support frame needs to be removed first. , and then dismantle the formwork, the dismantling steps are cumbersome, and the dismantling of the formwork is difficult.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a single-sided wall formwork trolley in view of the above-mentioned problems, which can facilitate erecting and demoulding, improve construction efficiency and reduce artificial fatigue strength.

The technical scheme adopted in the present invention is as follows:

A single-sided wall formwork trolley includes a car body, a support frame and a formwork; the car body includes a chassis, a lifting mechanism, a translation mechanism and a walking mechanism; the lifting mechanism is arranged below the chassis, and the upper end of the lifting mechanism is connected to the The bottom of the chassis is connected, and the lower end is provided with a walking mechanism, and the lifting mechanism is used to drive the chassis to rise and fall; the translation mechanism is arranged on the top of the chassis; the back of the template is arranged on the support frame; the lower end of the support frame is hinged on the translation mechanism Above, the translation mechanism is used to drive the support frame to move horizontally; a demolding mechanism is arranged between the support frame and the translation mechanism, and the demolding mechanism is used to drive the support frame to rotate relative to the vehicle body in the vertical plane.

Due to the above structure, when the mold cavity needs to be constructed with the soil wall or the surrounding wall, the demolding mechanism pushes the support frame to rotate, so that the template stands up to form the mold cavity. Then, the up and down position of the template can be adjusted by the up and down movement of the lifting mechanism, and the template can be moved horizontally by the translation mechanism to adjust the position of the template to the soil wall or fence. After the pouring is completed, the demoulding mechanism drives the support frame to rotate, so that the support frame rotates in the direction of the chassis, and then the formwork is separated from the poured wall surface to complete the demoulding. According to the present invention, the position adjustment of the template in the vertical mold process can be realized by the cooperation of the lifting mechanism, the translation mechanism and the demolding mechanism, which saves manpower; the support frame does not need to be removed during the demoulding process, and the demoulding mechanism can easily drive the template from the wall. The surface falls off, making the whole demoulding process more convenient.

Further, the lifting mechanism is a lifting cylinder, the upper end of the lifting cylinder is connected with the bottom of the chassis, and the lower end of the lifting cylinder is connected with the traveling mechanism.

Further, the walking mechanism includes a track, a wheel frame, a driving wheel, a driven wheel and a driving motor for the driving wheel; the wheel frame is arranged at the lower end of the lifting mechanism, and the driving wheel, the driven wheel and the driving motor for the driving wheel are arranged on the wheel. On the frame, the driving wheel and the driven wheel are arranged on the track, and the driving motor of the driving wheel is used to drive the driving wheel to rotate, so that the moving mechanism drives the vehicle body to move along the track.

Further, the translation mechanism includes two rows of sliding rollers arranged in parallel on the top of the chassis, and a translation plate is arranged above the sliding rollers; The rolling surface is embedded in the chute and is in contact with the bottom of the chute; the chassis is provided with a translation plate drive mechanism, which is located at the rear end of the translation plate and is used to drive the translation plate to reciprocate along the arrangement direction of the sliding rolls , making the template close to or away from the cavity; the lower end of the support frame is hinged on the translation plate.

In the above structure, if the translation plate is matched by sliding rails and sliding rollers, derailment is likely to occur, and a rail clamping mechanism needs to be added, which will cause the structure to become complicated. At the same time, if the track is set on the chassis, and the sliding plate is set at the bottom of the translation plate, in order to maintain the balance of the translation plate, the front and rear ends of the translation plate should be set to contact the sliding roller and the sliding rail, then when the translation plate moves to the mold cavity, When extending the chassis, the rollers may hang in the air, and when the pans are retracted, the rollers and the rails may collide. However, in the present invention, the chute is arranged on the translation plate and then cooperates with the sliding roller, so that the above problems can be avoided, and the structure is simple.

Further, the translation plate driving mechanism is a translation oil cylinder, one end of the translation oil cylinder is fixedly arranged on the chassis, and the other end is connected to the rear end of the translation plate.

Further, the demoulding mechanism is a demoulding cylinder, one end of the demolding cylinder is hinged on the support frame, and the other end is hinged on the translation plate, when the piston rod of the demoulding cylinder extends out of the cylinder, the supporting frame is turned upwards. Away from the translation plate, when the piston rod of the demolding cylinder retracts into the cylinder, the support frame flips down to approach the translation plate.

Due to the above structure, the use of an air cylinder to complete the demoulding of the template has high demoulding efficiency and labor saving, and reduces artificial fatigue strength.

Further, the demolding mechanism is a telescopic arm, and the telescopic arm includes an arm body 1 and an arm body 2; The body 1 and the arm body 2 can move relatively in the length direction; the other end of the arm body 1 is hinged on the support frame, and the other end of the arm body 2 is hinged on the translation plate; the outer side wall of the telescopic arm A telescopic arm cylinder is arranged on it, one end of the telescopic arm cylinder is connected to the outer side wall of the first arm body, and the other end is connected to the outer side wall of the arm body two; when the piston rod of the telescopic arm cylinder extends out of the cylinder body, the telescopic arm extends long, the support frame is turned up and away from the translation plate, when the piston rod of the telescopic arm cylinder is retracted into the cylinder, the support arm is contracted, and the support frame is turned down and close to the translation plate.

If the cylinder is directly used to support the support frame, the size of the entire cylinder will become very large, and the cylinder body and the piston rod will be made very long. Therefore, in the present invention, a telescopic arm is used to support the support frame, and then the cylinder is used to drive the support frame. The telescopic arm is telescopic, which can reduce the size of the cylinder.

Further, a number of reinforced support rods are also arranged between the support frame and the translation plate. One end of the reinforcement support rod is hinged on the support frame, and the other end is hinged on the translation plate. When the reinforcement support rod is retractable, the support frame It can be rotated relative to the translation plate in the vertical plane, and when the reinforcing support rod is not telescopic, the support frame is restricted from rotating relative to the translation plate in the vertical plane.

Due to the above structure, when the position of the support frame is fixed, the movement of the support frame is further restricted by strengthening the support rod, so as to ensure the safety in the whole work project. The reinforced support rod can be retracted, and the support frame can be rotated without removing the support rod, which is convenient for mold erection and demoulding.

Further, the reinforcing support rod includes a hollow support section 1 and a support section 2, one end of the support section 1 is inserted into one end of the support section 2, and in the length direction of the support section 1 and the support section 2, the support section Section 1 and support section 2 can move relative to each other; along the length direction of support section 1 and support section 2, a number of adjustment holes are opened on the side walls of the support section 1 and support section 2, and the adjustment holes are arranged in equal intervals. In a row, it runs through the side walls of the first and second supporting sections; when the bolts are inserted into the adjusting holes of the first and second supporting sections, the relative movement of the first and second supporting sections is restricted; One end is hinged on the support frame, and the other end of the second support segment is hinged on the translation plate.

Due to the above structure, when the support frame is to be rotated, the bolts can be pulled out from the adjustment holes in the support section 1 and the support section 2. When it is necessary to ensure the stability of the working position of the support frame, the bolts are inserted into the adjustment holes in the support section 1 and the support section 2 to limit the expansion and contraction of the reinforcing support rod.

Further, when the template is perpendicular to the chassis, at least one adjustment hole on the first support section and the second support section is aligned with each other. Ensure that when the template is in the working position, the bolts can be inserted into the adjustment holes to limit the expansion and contraction of the reinforcing support rods.

Further, the bottom of the chassis is provided with a support leg, and the support leg is a jack; or the support leg includes a foot and a screw rod, and the upper end of the screw rod is inserted into the chassis and is threadedly connected with the chassis, and the bottom foot It is fixedly arranged at the lower end of the screw rod, and when the screw rod rotates, the height of the support leg can be adjusted.
