Description

Concrete trolleys for building construction

technical field

The utility model relates to building construction equipment, in particular to a concrete trolley for building construction.

Background technique

Due to the complex construction environment during building construction, some large-scale transportation machinery cannot be used conveniently. In this case, the transportation of some building materials such as concrete requires small and convenient trolleys. We can see that trolleys are essential at the construction site. Fewer means of transportation brings great convenience to construction. Through observation, it is found that when transporting building materials to the destination for unloading, construction personnel generally use two methods: one is to divide the goods in the trolley into several times. To unload, the second is to push the trolley violently and use the inertia to tip the trolley, and the goods are unloaded. There is a certain risk in the second method; although the first method is safe, it is time-consuming and labor-intensive. Therefore a kind of hand barrow that is convenient to tipping and can unload fast just seems extremely necessary.

Contents of the invention

In view of the above situation, in order to overcome the defects of the prior art, the purpose of this utility model is to provide a concrete trolley for building construction, which can effectively solve the problem that the existing trolley is not easy to tip over and unloads.

The technical solution is a concrete trolley for building construction, including a car body with handrails, a base is provided at the lower end surface of the bottom of the car body, the bottom of the base is connected with a wheel through a bearing, and the base forms a rotation with the left end of the car body. Connection, the right end of the car body forms a fixed connection with the base through a lock.

The utility model is simple in structure and easy to operate. When unloading, you only need to open the lock at the right end of the car body, and the car body can be separated from the base, which is convenient for the car body to tip over, and it is easy to unload the building materials in the car body at one time. It's quick and easy.

Detailed ways

The specific embodiments of the present utility model will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figures 1-4, a concrete trolley for building construction includes a car body 1 with handrails, a base 2 is provided at the lower end surface of the bottom of the car body 1, and the base 2 forms a rotational connection with the left end of the car body 1 , the right end of the car body 1 forms a fixed connection with the base 2 through a lock.

In order to ensure the specific implementation effect, the upper end surface of the left end of the base 2 is provided with a hinged support 3, and the hinged support 3 forms the said rotational connection with the vehicle body 1 through a pin shaft, and the lower end surface of the left end of the base 2 is provided with Vertical short rod 4, the short rod 4 is fixedly connected with the lower end surface of the base, the lower end of the short rod 4 is 20-25 cm away from the ground, the upper end surface of the right end of the base 2 is provided with a positioning pin 5, and the lower end surface of the right end of the base 2 is provided with At least two vertical support rods 6, the upper ends of the support rods 6 are fixedly connected to the lower end surface of the base, a crossbeam 7 is arranged between the two support rods, the middle part of the crossbeam 7 is connected with a pedal 8 through the hinged support 3, and the two upper ends of the pedal 8 Tensioned first springs 9 are respectively connected to the sides, the other end of the first spring 9 is fixedly connected to the beam 7 , and the upper end of the pedal 8 is provided with a first locking hook 10 .

In order to ensure the specific implementation effect, the lower end surface of the bottom of the car body 1 is provided with a mounting hole 11 corresponding to the positioning pin 5, the internal diameter of the mounting hole 11 is greater than the external diameter of the positioning pin 5, and a spring is fixed in the mounting hole 11. Nut 12, the second spring 13 that inner diameter and locating pin 5 outer diameters are adapted on the spring nut 12, the second locking hook 14 corresponding with the first locking hook 10 is housed on the lower end portion outer surface of car body 1 right-hand side, constitutes The right end of said vehicle body 1 is fixedly connected to the base 2 through a lock.

In order to ensure specific implementation effect, said base is provided with mounting frame 15, and mounting frame 15 is connected with wheel 16 by bearing.

In order to ensure the specific implementation effect, when the first spring is installed, the tension of the first spring should not be too tight, and it is appropriate for ordinary people to lightly step on the pedal to complete the detachment of the first lock hook and the second lock hook.

When the utility model is unloading, the operator only needs to step on the pedal 8, the car body 1 is lifted up under the elastic force of the second spring 13, the first lock hook 10 and the second lock hook 14 are disengaged, and the operator holds the car body 1 The handrail pushes the car body 1 upwards. As the front end of the car body 1 tilts downward, the short rod 4 at the left end of the base 2 touches the ground. Continue to rotate around the left end of the base 2 to complete the tipping action, and the goods inside the car body 1 are also unloaded along with the tipping action; Covered on the positioning pin, the first lock hook 10 and the second lock hook 14 are locked under the action of the first spring 9, the car body 1 and the base 2 complete the fixing action, and the trolley can be put into the next operation again.

The utility model is simple in structure and easy to operate. When unloading, you only need to open the lock at the right end of the car body, and the car body can be separated from the base, which is convenient for the car body to tip over, and it is easy to unload the building materials in the car body at one time. It's quick and easy.
