Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete mixing tank truck elevator. Background Art

[0002] In some places where it is inconvenient to use concrete pump trucks, such as overpasses and high-rise buildings, lifting equipment is generally used to lift the mixing tank truck to the platform where concrete needs to be poured, and then the concrete mixing tank truck is used to dump the concrete for pouring operations.

[0003] When the existing concrete mixer truck elevator is in operation, the staff usually drives the mixer truck onto the elevator, and then lifts the mixer truck and the driver together through the elevator. This is unsafe. The weight of the mixer truck plus the weight of the concrete causes a large load on the elevator, so the braking and anti-fall effect will also be affected. If the operator is also on the mixer truck elevator, it is easy for people to fall and even be injured, killed, or even crushed to death. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a concrete mixing tank truck elevator to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete mixer truck elevator, comprising a lower seat and a lifting platform, the top of the lifting platform is respectively provided with a second roller and a guide rail, and a linear motor is installed inside the guide rail, the output end of the linear motor is connected to a parking plate, and the outer surface of the parking plate is connected to a first roller, and the top of the parking plate is connected to a resistance bar.

[0006] By adopting the above technical solution, the staff will drive the mixer truck to the parking board, pull the handbrake, get off the car and move away from the elevator. At the same time, the forward and backward methods of the vehicle are blocked by the resistance bar, and the handbrake is used to effectively prevent the vehicle from detaching from the parking board. When the mixer truck is lifted to the upper seat, the linear motor drives the parking board to move, and the parking board and the mixer truck on the parking board are removed from the elevator. After that, the staff on the building can drive away the mixer truck, or wait for the staff under the building to take the staff-only elevator to move to the building and drive away the mixer truck; after the mixer truck has dumped the concrete, the staff will drive the mixer truck to the parking board again and pull the handbrake, and then the staff will move away. The parking board is moved back to the top of the lifting platform by the linear motor. After the lifting platform descends to the lower seat, the staff will get on the car and drive away the mixer truck.

[0007] Furthermore, the parking plate is slidably connected to the lifting platform.

[0008] By adopting the above technical solution, the linear motor drives the parking plate to move, and the parking plate and the mixer truck on the parking plate are removed from the elevator, without the need for workers to enter the upper seat, thereby improving safety.

[0009] Furthermore, a plurality of the first rollers and the second rollers are provided, and the plurality of first rollers are distributed at equal intervals, and the plurality of second rollers are distributed in a rectangular array.

[0010] By adopting the above technical solution, the friction between the parking plate and the lifting platform, the upper seat and the building is reduced by the first roller and the second roller, thereby reducing structural wear.

[0011] Furthermore, the parking plate is in contact with the second roller.

[0012] By adopting the above technical solution, the linear motor drives the parking plate to move, and the parking plate and the mixer truck on the parking plate are removed from the elevator, and the wear between the parking plate and the lifting platform is reduced by the second roller.

[0013] Furthermore, there are two said bars, and the two bars are symmetrically distributed.

[0014] By adopting the above technical solution, the forward and backward movement of the vehicle is blocked by the resistance bar, and the handbrake is used to effectively prevent the vehicle from falling off the parking board.

[0015] Furthermore, brackets are fixed on both sides of the top of the lower seat, and the upper seat is fixed on the top of the brackets, a top frame is fixed on the top of the upper seat, a crane is installed on the top of the top frame, and the lifting platform is connected to the output end of the crane.

[0016] By adopting the above technical solution, after the mixing tank truck is parked, the staff will open the crane, and after the crane is turned on, it will drive the lifting platform to move up, so that the mixing tank truck is lifted to the upper seat, thereby facilitating the lifting of the mixing tank truck.

[0017] Furthermore, the outer surface of the lower seat is provided with a slope.

[0018] By adopting the above technical solution, the slope of the outer surface of the lower seat makes it easier for workers to drive the mixing tank truck to the top of the parking plate, making it convenient for people to enter and exit.

[0019] Furthermore, a first human body detection sensor is installed on the back of the lower seat, and a second human body detection sensor is installed on the back of the upper seat.

[0020] By adopting the above technical solution, if a person does not leave the cab of the mixing tank truck, he or she will be detected by the first human detection sensor or the second human detection sensor, thereby making the elevator unable to work.

[0021] In summary, the present invention has the following beneficial effects:

[0022] After the concrete is poured by the concrete mixer truck, the staff will drive the concrete mixer truck to the parking board again and pull the handbrake, then the staff will move away, and then the staff will move the concrete mixer truck back to the top of the lifting platform by the linear motor. After the lifting platform is lowered to the lower seat, the staff will get on the vehicle and drive away the concrete mixer truck. There is no person on the elevator during the lifting process, which effectively avoids personal injury caused by falling and improves safety.

[0023] 2. The utility model provides the first roller and the second roller. When the linear motor drives the parking plate to move, the first roller and the second roller are used to reduce the friction between the parking plate and the lifting platform, the upper seat and the building, thereby reducing structural wear and improving the service life of the parking plate.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] The following describes an embodiment of the present invention based on its overall structure.

[0031] Example 1:

[0032] A concrete mixer truck elevator, such as Figure 1-Figure 3 As shown, it includes a lower seat 1 and a lifting platform 6, and a second roller 10 and a guide rail 11 are respectively provided on the top of the lifting platform 6. A linear motor 12 is installed inside the guide rail 11, and the output end of the linear motor 12 is connected to the parking plate 7, and the parking plate 7 is slidably connected to the lifting platform 6. The linear motor 12 drives the parking plate 7 to move, and moves the parking plate 7 and the mixer truck on the parking plate 7 out of the elevator; the outer surface of the parking plate 7 is connected to the first roller 8, and the first roller 8 and the second roller 10 are both provided. The multiple first rollers 8 are equidistantly distributed, and the multiple second rollers 10 are distributed in a rectangular array. The parking plate 7 is in contact with the second roller 10, and the friction between the parking plate 7 and the lifting platform 6, the upper seat 3 and the building is reduced by the first roller 8 and the second roller 10, thereby reducing structural wear; the top of the parking plate 7 is connected to a stop bar 9, and there are two stop bars 9, which are symmetrically distributed. The stop bars 9 block the forward and backward methods of the vehicle, and cooperate with the handbrake to effectively prevent the vehicle from detaching from the parking plate 7.

[0033] See Figure 1 and Figure 4 In the above embodiment, the outer surface of the lower seat 1 is provided with a slope, and brackets 2 are fixed on both sides of the top of the lower seat 1, the upper seat 3 is fixed on the top of the bracket 2, and the top frame 4 is fixed on the top of the upper seat 3 to form a supporting structure; a jack 5 is installed on the top of the top frame 4, and a lifting platform 6 is connected to the output end of the jack 5. After the jack 5 is turned on, the lifting platform 6 is driven to move upward, so that the mixing tank truck is lifted to the upper seat 3, or the lifting platform 6 is driven to move downward, so that the mixing tank truck is returned to the lower seat 1.

[0034] Example 2:

[0035] On the basis of the above embodiment 1, in order to improve safety and avoid workers on the lifting platform, the following settings are now adopted.

[0036] See Figure 4 In the above embodiment, a first human detection sensor 13 is installed on the back of the lower seat 1, and a second human detection sensor 14 is installed on the back of the upper seat 3. If a person does not leave the cab of the mixer truck, he will be detected by the first human detection sensor 13 or the second human detection sensor 14, thereby making the elevator unable to work.

[0037] The working principle of the present invention is as follows: after the worker drives the mixing tank truck onto the parking plate 7, he pulls the handbrake and then gets off the truck away from the elevator. If the worker does not leave the cab of the mixing tank truck, he will be detected by the first human detection sensor 13 or the second human detection sensor 14, so that the elevator cannot work. At the same time, the forward and backward movement of the vehicle is blocked by the stop bar 9, and the handbrake is used to effectively prevent the vehicle from leaving the parking plate 7.

[0038] After the mixing tank truck is parked, the staff will open the jack 5, which will drive the lifting platform 6 to move up, so that the mixing tank truck is lifted to the upper seat 3. Then the linear motor 12 drives the parking plate 7 to move, and the parking plate 7 and the mixing tank truck on the parking plate 7 are moved out of the elevator. At the same time, the first roller 8 and the second roller 10 are used to reduce the friction between the parking plate 7 and the lifting platform 6, the upper seat 3 and the building, thereby reducing structural wear. After that, the staff on the building can drive away the mixing tank truck, or wait for the staff under the building to take the personnel-only elevator to move to the building to drive away the mixing tank truck;

[0039] After the mixer truck has finished dumping the concrete, the staff will drive the mixer truck to the parking plate 7 again and pull the handbrake. The staff will then move away and move the parking plate 7 back to the top of the lifting platform 6 through the linear motor 12. After the lifting platform 6 descends to the lower seat 1, the staff will get on the car and drive away the mixer truck.

[0040] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
