Description

Technical Field

[0001] The invention relates to a scissor lift concrete conveying device and a conveying method. Background Art

[0002] Generally, traditional concrete conveying hoppers are discharged into them by a high-level mixing station installed above them. After being filled with materials, the hopper moves along the track, and when it reaches the top of the concrete placing boom, it discharges materials into the concrete placing boom. When there is no high-level mixing station, a low-level loading hopper is used. This loading method first lowers the hopper to the ground, and then uses a concrete tank truck to load the hopper. After being filled with materials, the hopper is lifted up by a winch, and then moves along the track to the top of the concrete placing boom to discharge materials into the concrete placing boom. The use of a winch for lifting requires a relatively large space in the factory building. When the factory building is not high enough, the hoisting mechanism of the winch is limited by space. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a scissor lift concrete conveying device and a conveying method which are easy to operate, stable and reliable, and save space.

[0004] The present invention adopts the following technical solution:

[0005] The scissor-type lifting concrete conveying device of the present invention comprises frame pillars arranged at intervals on the ground, running tracks fixedly installed on the tops of the frame pillars, a conveying trolley running on the running tracks, a scissor-type lift arranged in a foundation pit below the running tracks, and a separation hopper arranged on the top of the scissor-type lift; the corresponding sides of the conveying trolley and the separation hopper are open; the conveying trolley is located between the running tracks; the scissor-type lift rises, driving the separation hopper to rise, so that the conveying trolley forks the separation hopper.

[0006] The separation hopper of the scissor-type lifting concrete conveying device of the present invention comprises a rectangular support frame, an open hopper body arranged on the support frame, and discharge baffles arranged on both sides of the bottom of the hopper body, and support feet are fixedly installed at the two end parts of the outer sides of the two frame frames of the hopper body respectively; a guide inclined surface is arranged on the outer side of the bottom of the support foot, and a load-bearing surface connected to the guide inclined surface is arranged at the bottom of the support foot; the conveying trolley is a U-shaped fork, running wheels are installed at the bottom of the conveying trolley, and concave support seats matching the support feet are arranged on the inner sides of the two frame frames of the conveying trolley, and the surface of the inner side of the concave support seat corresponding to the guide inclined surface is an inclined surface.

[0007] The scissor-fork lifting concrete conveying device of the present invention has a non-powered cable drum installed on a conveying trolley, and one end of a cable on the non-powered cable drum is connected to a separation hopper.

[0008] The scissor lift concrete conveying device of the present invention has guide frames installed on the corresponding sides of the frame pillars, and the two ends of the scissor lift are arranged in the guide grooves between the guide frames.

[0009] The scissor lift concrete conveying device of the present invention has limit baffles arranged at four corners of the top plate of the scissor lift, and the bottom of the support frame is arranged inside the limit baffles.

[0010] The scissor lift concrete conveying method of the present invention adopts the following conveying steps:

[0011] Step 1: At the beginning, the scissor lift and the separation hopper are both set in the foundation pit, and the bottom of the support frame is set on the inner side of the limit baffle of the top plate of the scissor lift. The separation hopper is raised to partially or completely rise out of the foundation pit, so that the concrete tank truck is suitable for stopping when adding materials;

[0012] Step 2: The concrete tanker drives to the outside of the separation hopper and stops, fills the separation hopper with the mixed concrete and then drives away; start the scissor lift, which drives the separation hopper to rise along the guide frame. The separation hopper stops when the bottom of the support foot is slightly higher than the top surface of the conveying trolley. Start the conveying trolley to drive it under the hopper body, and then the scissor lift drives the separation hopper to fall, so that the corresponding support foot falls into the corresponding concave support seat, and the separation hopper and the conveying trolley are combined into one;

[0013] Step 3: The scissor lift falls, so that the limit baffle is separated from the support frame, and the conveying trolley is started. The conveying trolley drives the separation hopper to run on the running track and stops above the concrete placing boom. The discharge baffle at the bottom of the separation hopper is started to open, so that the concrete falls into the concrete placing boom;

[0014] Step 4: After the material is dropped, the discharge baffle is closed, and the conveyor trolley drives the separation hopper to run on the running track to the top of the scissors-type lift. The scissors-type lift rises, and the scissors-type lift holds the support frame of the separation hopper and rises slightly to make the support feet separate from the concave support seat, and the conveyor trolley drives away from the hopper body; the scissors-type lift drives the separation hopper down back into the foundation pit, waiting for the ground equipment to add material to it. After the adding is completed, it can be raised again to start the next operation cycle.

[0015] The scissors-type lifting concrete conveying method of the present invention also includes the step of cleaning the separation hopper, lowering the scissors-type lift until its top surface is flush with the top of the foundation pit, pushing the cleaning waste receiving trolley between the limit baffles set at the four corners of the top plate of the scissors-type lift, and then performing the process of raising and receiving the separation hopper by the scissors-type lift in step four, and stopping when the scissors-type lift drives the separation hopper downward to a position convenient for cleaning operation, adding water to the separation hopper to clean its inner cavity, starting to open the discharge baffle at the bottom of the separation hopper, pouring the cleaned waste into the cleaning waste receiving trolley, and then the scissors-type lift drives the cleaning waste receiving trolley to adjust its position to be flush with the ground, and pushing the cleaning waste receiving trolley away from the top surface of the scissors-type lift.

[0016] The invention discloses a scissor lift concrete conveying method, wherein a cleaning waste receiving trolley comprises a vehicle body and wheels arranged at the bottom of the vehicle body, the vehicle body is conical, and a handle is arranged at one end of the vehicle body.

[0017] The positive effects of the present invention are as follows: the starting positions of the scissor lift and the separation hopper of the present invention are set in the foundation pit, and the separation hopper is lifted and lowered by the scissor lift, which does not occupy the upper space of the factory building, and can use the limited height to meet the lifting stroke of the separation hopper. The two ends of the scissor lift are set in the guide grooves between the guide frames, so that the shaking of the top bearing surface of the scissor lift during the lifting process is greatly reduced, avoiding the inability to accurately position and connect the hopper body and the conveying trolley. The support foot can be accurately positioned in the concave support seat; the outer side of the support foot is provided with a guide slope, and the support foot and the concave support seat are separated each time and then dropped back to the position, which can accurately position the separation hopper and the conveying trolley after repeated actions. The non-powered cable reel is controlled by uninterrupted power supply, and can realize the transmission of multiple power lines and control signal lines, so that the separation hopper body and the conveying trolley will not be too far apart even if they are separated. In this way, whether the two are separated or combined into one, the power supply and signal connection lines between them can be kept unobstructed, so that the electric control actions of the separation hopper body and the conveying trolley are organically combined and will not be separated. The cleaning waste receiving trolley can be used to receive the cleaning waste from the hopper body to keep the separation hopper clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The separation hopper 5 of the device of the present invention includes a rectangular support frame 51, an open hopper body 52 arranged on the support frame 51, and a discharge baffle 53 arranged on both sides of the bottom of the hopper body 52, and the two ends of the outer sides of the two frame of the hopper body 52 are fixedly installed with support feet 7 respectively; a guide slope 72 is arranged on the outer side of the bottom of the support foot 7, and a load-bearing surface 71 connected with the guide slope 72 is arranged at the bottom of the support foot 7; the conveying trolley 3 is a U-shaped fork, and a running wheel 8 is installed at the bottom of the conveying trolley 3, and a concave support seat 9 matching the support foot 7 is arranged on the inner sides of the two frame of the conveying trolley 3, and the inner side of the concave support seat 9 corresponding to the guide slope 72 is a slope, and this slope is parallel to the guide slope 72, so that the support foot 7 is accurately positioned in the concave support seat 9, and the load-bearing surface 71 is in contact with the top surface of the concave support seat 9 for bearing weight. A non-powered cable drum 10 is installed on the conveying trolley 3, and one end of the cable on the non-powered cable drum 10 is connected to the separation hopper 5. The scissor lift 4 and the non-powered cable drum 10 are both commercially available.

[0032] A guide frame is installed on the corresponding side of the frame support 1, and the two ends of the scissor lift 4 are arranged in the guide grooves between the guide frames; so that the shaking of the top bearing surface of the scissor lift 4 during the lifting process is greatly reduced, and the hopper body and the conveying trolley 3 cannot be accurately positioned and connected. The four corners of the top plate of the scissor lift 4 are provided with limit baffles 11, and the support frame 51 is arranged inside the baffles 11.

[0033] As attached Figure 1-9 As shown, the scissor lift concrete conveying method of the present invention adopts the following conveying steps:

[0034] Step 1: At the beginning, the scissor lift 4 and the separation hopper 5 are both set in the foundation pit 6, and the bottom of the support frame 51 is set inside the limit baffle 11 of the top plate of the scissor lift 4, and the separation hopper 5 is raised to partially or completely rise out of the foundation pit 6, so that the concrete tanker 12 is suitable for stopping when adding materials, that is, the height is appropriate, which is convenient for receiving materials;

[0035] Step 2: The concrete tanker 12 drives to the vicinity of the outer side of the separation hopper 5 and stops, fills the separation hopper 5 with the mixed concrete material and then drives away; the scissor lift 4 is started, and the scissor lift 4 drives the separation hopper 5 to rise along the guide frame, and the separation hopper 5 is raised to the point where the bottom of the support leg 7 is slightly higher than the top surface of the conveying trolley 3 and stops, and the conveying trolley 3 is started to drive it under the hopper body 52, and then the scissor lift 4 drives the separation hopper 5 to fall, so that the corresponding support leg 7 falls into the corresponding concave support seat 9, and the separation hopper 5 is combined with the conveying trolley 3 as a whole;

[0036] Step 3: The scissor lift 4 falls, so that the limit baffle 11 is separated from the support frame 51, and the conveying trolley 3 is started. The conveying trolley 3 drives the separation hopper 5 to run on the running track 2, and stops when it reaches the top of the concrete distributor 13. The discharge baffle 53 at the bottom of the separation hopper 5 is started to open, so that the concrete falls into the concrete distributor 13;

[0037] Step 4: After the material is dropped, the discharge baffle 53 is closed, and the conveying trolley 3 drives the separation hopper 5 to run on the running track 2 to the top of the scissor-type lift 4. The scissor-type lift 4 rises, and the scissor-type lift 4 holds the support frame 51 of the separation hopper 5 and then rises slightly, so that the support foot 7 is separated from the concave support seat 9, and the conveying trolley 3 drives away from the hopper body 52; the scissor-type lift 4 drives the separation hopper 5 to descend back into the foundation pit 6, waiting for the ground equipment to add material to it. After the material is added, it can be raised again to start the next operation cycle.

[0038] The method of the present invention also includes the step of cleaning the separation hopper 5, lowering the scissors-type lift 4 until its top surface is flush with the top of the foundation pit, pushing the cleaning waste receiving trolley 14 to between the limit baffles 11 set at the four corners of the top plate of the scissors-type lift 4, and then performing the process of raising the scissors-type lift 4 and receiving the separation hopper 5 in step 4, and stopping when the scissors-type lift 4 drives the separation hopper 5 to descend to a position convenient for cleaning operation, adding water to the separation hopper 5 to clean its inner cavity, starting the discharge baffle 53 at the bottom of the separation hopper 5 to open, and after pouring the cleaned waste into the cleaning waste receiving trolley 14, the scissors-type lift 4 drives the cleaning waste receiving trolley 14 to adjust its position so that the cleaning waste receiving trolley 14 is flush with the ground, and the cleaning waste receiving trolley 14 is pushed away from the top surface of the scissors-type lift 4. The cleaning waste receiving trolley 14 includes a body 141 and wheels arranged at the bottom of the body 141. The body is conical, and a handle 142 for convenient hand pushing and pulling is arranged at one end of the body 141.

[0039] The starting positions of the scissor-type lift 4 and the separation hopper 5 of the present invention are set in the foundation pit. The separation hopper 5 is lifted and lowered by the scissor-type lift 4, which does not occupy the upper space of the factory building and can use the limited height to meet the lifting stroke of the separation hopper 5. The two ends of the scissor-type lift 4 are set in the guide grooves between the guide frames, so that the shaking of the top bearing surface of the scissor-type lift 4 during the lifting process is greatly reduced, avoiding the inability to accurately position and connect the hopper body and the conveying trolley 3. The support foot can be accurately positioned in the concave support seat 9; the outer side of the support foot is an inclined surface, and the support foot and the concave support seat 9 are separated each time and then dropped back to their original position. They can all be accurately positioned, avoiding the position drift of the separation hopper 5 and the conveying trolley 3 after repeated actions. The non-powered cable reel 10 is controlled by uninterrupted power supply, and can realize the transmission of multiple power lines and control signal lines, so that the separation hopper body and the conveying trolley 3 will not be too far apart even if they are separated. In this way, whether the two are separated or combined into one, the power supply and signal connection lines between them can remain unobstructed, so that the separation hopper body and the electric control action of the conveying trolley 3 are organically combined and will not be cut. The cleaning waste receiving trolley 14 can be used to receive the cleaning waste of the hopper body to keep the separation hopper clean.
