Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying equipment technology, and in particular to a gantry concrete placing machine. Background Technology
[0002] To facilitate unloading at any position on the belt conveyor, a movable unloading trolley is installed on the belt conveyor along the length of the conveyor belt. An unloading belt is installed on the unloading trolley. By moving the unloading trolley along the length of the conveyor belt, unloading can be achieved at any position within the range of its travel distance, thereby realizing multi-point material conveying.
[0003] However, the commonly used unloading trolleys currently use a funnel-extending belt conveyor on one or both sides to unload materials. Since the distance the funnel extends out of the conveyor is limited, the material distribution distance is short. Moreover, since the material drop of the unloading trolley is fixed, in order to improve the storage yield, the material generally needs to be screened twice after unloading. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a gantry fabric feeding machine that increases the fabric feeding distance and allows for adjustment of the fabric drop.
[0005] To achieve the above objectives, this utility model is implemented according to the following technical solution:
[0006] A gantry conveyor includes a belt conveyor. The belt conveyor has a self-propelled gantry frame that can move along its length in the width direction. A pitching belt conveyor is located at the top of the self-propelled gantry frame. The pitching belt conveyor includes a receiving section belt conveyor fixed to the top of the self-propelled gantry frame and a placing section belt conveyor located outside the belt conveyor. The receiving section belt conveyor and the belt conveyor are spatially perpendicular. The rear end of the placing section belt conveyor's frame is hinged to one end of the upper surface of the self-propelled gantry frame. A drive mechanism for changing the pitch angle of the placing section belt conveyor is installed at the bottom of the outer side wall of one end of the self-propelled gantry frame. A movable unloader is provided on the frame of the receiving section belt conveyor. The loading end of the movable unloader extends above the belt conveyor, and the unloading end of the movable unloader is located above the receiving section belt conveyor.
[0007] Furthermore, the driving mechanism includes a hydraulic cylinder, the end of which is hinged to the bottom of the outer side wall of one end of the self-propelled gantry frame, and a sleeve is hinged to the end of the top rod of the hydraulic cylinder. The sleeve is slidably mounted on the slide rod, and the slide rod is fixed to the lower part of the frame of the fabric section belt conveyor by a mounting bracket.
[0008] Furthermore, the slide bar is located at the lower rear end of the frame of the fabric section conveyor, and the slide bar is parallel to the lower end face of the frame of the fabric section conveyor.
[0009] Furthermore, the self-propelled gantry frame includes a gantry frame and tracks fixed on both sides of the belt conveyor in the width direction. A U-shaped groove is formed on the lower bottom surface of the gantry frame. Bearings are installed in the two side walls of the U-shaped groove. Track wheels that slide with the tracks are provided in the U-shaped groove. A rotating shaft is fixedly installed at the center of the track wheels. Both ends of the rotating shaft are axially fixed in the inner rings of the bearings. One end of the rotating shaft extends through one side wall of the U-shaped groove to the outside of the side wall of the gantry frame. A brake reduction motor is fixedly installed on one side of the bottom of the gantry frame. The output end of the brake reduction motor is axially fixedly connected to one end of the rotating shaft.
[0010] Compared with the prior art, this utility model sets up a self-propelled gantry that can move along the length of the belt conveyor, and sets up a pitching belt conveyor for material distribution on the self-propelled gantry. The unloading trolley on the pitching belt conveyor can transfer the material on the belt conveyor to the pitching belt conveyor. Since the front end of the pitching belt conveyor extends to the outside of the belt conveyor, the material distribution distance of the material distributor is increased. At the same time, during material distribution, the pitching angle of the pitching belt conveyor can be adjusted by hydraulic cylinder to adjust the material drop, improve the storage yield, eliminate the need for secondary screening process, and ensure the particle size quality of stored materials.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model.
[0016] like Figure 1 , Figure 2As shown in the illustration, this embodiment exemplarily demonstrates a gantry fabric placing machine, including a belt conveyor 1. The belt conveyor 1 has a self-propelled gantry frame 2 that can move along its length in the width direction. A pitching belt conveyor is located at the top of the self-propelled gantry frame 2. The pitching belt conveyor includes a receiving section belt conveyor 3 fixed to the top of the self-propelled gantry frame 2 and a placing section belt conveyor 4 located outside the belt conveyor. The receiving section belt conveyor 3 is spatially perpendicular to the belt conveyor 1. The rear end of the frame of the placing section belt conveyor 4 is hinged to one end of the upper surface of the self-propelled gantry frame 2 via a hinge seat 5. A drive mechanism for changing the pitch angle of the fabric conveyor belt is installed on the bottom of the outer side wall of one end of the self-propelled gantry frame 2; a mobile unloader 6 is provided on the frame of the receiving section conveyor belt 3. The loading end of the mobile unloader 6 extends above the belt conveyor 1, and the unloading end of the mobile unloader 6 is located above the receiving section conveyor belt 3. The mobile unloader 6 is a conventional unloading trolley for unloading on a belt conveyor. Existing unloading trolleys can be used directly. Its specific structure will not be described in this embodiment. As long as the material on the belt conveyor 1 can be transferred to the receiving section conveyor belt 3, it is acceptable.
[0017] Specifically, the drive mechanism includes a hydraulic cylinder 10, the end of which is hinged to the bottom of the outer side wall of one end of the self-propelled gantry frame 2. A sleeve 9 is hinged to the end of the push rod of the hydraulic cylinder 10, and the sleeve 9 is slidably mounted on a slide rod 8. The slide rod 8 is fixed to the lower part of the frame of the fabric conveyor 4 via a mounting bracket 7. The slide rod 8 is located at the lower rear end of the frame of the fabric conveyor 4, and is parallel to the lower end face of the frame of the fabric conveyor 4. Figure 4 As shown, when the push rod of the hydraulic cylinder 10 retracts, it drives the fabric section belt conveyor 4 to rotate downward; conversely, the fabric section belt conveyor 4 rotates upward; thus, the pitch angle of the fabric section belt conveyor 4 can be adjusted to complete fabric laying at different angles.
[0018] Continue reading Figure 3 The self-propelled gantry frame 2 includes a gantry frame 21 and tracks 22 fixed on both sides of the belt conveyor 1 in the width direction. A U-shaped groove is formed on the lower bottom surface of the gantry frame 21. Bearings 25 are installed inside the two side walls of the U-shaped groove. Track wheels 23 are provided in the U-shaped groove and slide with the tracks. A rotating shaft 24 is fixedly mounted at the center of the track wheel 23. Both ends of the rotating shaft 24 are axially fixed in the inner rings of the bearings 25. One end of the rotating shaft 24 extends through one side wall of the U-shaped groove to the outside of the side wall of the gantry frame 21. A brake reduction motor 26 is fixedly installed on one side of the bottom of the gantry frame 21. The output end of the brake reduction motor 26 is axially fixedly connected to one end of the rotating shaft 24. The brake reduction motor 26 can drive the track wheels 23 to move independently on the tracks 22, increasing the range of fabric application.
[0019] like Figure 1 and Figure 4As shown, when the gantry concrete placing machine of this embodiment is used to place materials in the stockyard 11, the self-propelled gantry frame 2 moves along the length of the belt conveyor 1, while the moving unloader 6 transfers the material on the belt conveyor 1 to the receiving section belt conveyor 3. The receiving section belt conveyor 3 then transfers the material to the placing section belt conveyor 4, thereby transferring the material into the stockyard 11; Figure 1 As shown, the push rod of hydraulic cylinder 10 is in the extended position, and its drive to the fabric conveyor belt 4 is basically in a horizontal position; as Figure 4 As shown, when the push rod of the hydraulic cylinder 10 retracts, it drives the cloth section belt conveyor 4 to rotate downwards; this can adjust the pitch angle of the cloth section belt conveyor 4 to complete clothing at different angles; at the same time, during the clothing process, the pitch angle of the pitch belt conveyor can be adjusted at any time by the hydraulic cylinder to adjust the material drop, improve the storage yield, eliminate the need for secondary screening process, and ensure the particle size quality of stored materials.
