[0016] The beneficial effects of the lifting chamber and gantry-type fabric placing equipment provided in this embodiment of the utility model include: This application integrates the hopper door into the hopper body, allowing it to close under gravity. This eliminates the need for an additional power source for closing the door, resulting in a simple structure and low failure rate. The hopper door is equipped with an opening mechanism corresponding to the drive unit located on the concrete placing trolley. As the concrete placing trolley moves towards the bottom of the hopper after the lifting hopper has raised the concrete to a preset height, it moves the drive unit, which in turn pushes the opening mechanism to open the hopper door. This eliminates the need for manual opening, increasing efficiency. Furthermore, it eliminates the need for a motor or other drive mechanism within the lifting hopper, further simplifying its structure. Attached Figure Description

Detailed Implementation

[0020] Because gantry cranes are generally quite tall, cement mixer trucks typically cannot add precast concrete to placing booms. To address this issue, existing technologies generally employ a transfer mechanism using a lifting hopper that can move vertically. However, the discharge port of existing lifting hoppers usually needs to be manually opened, making the process cumbersome.

[0021] To address the aforementioned issues, this embodiment provides an lifting chamber and a gantry-type material placing device. The chamber's outlet door can be opened via a material placing trolley, eliminating the need for manual opening and thus increasing efficiency. Furthermore, it eliminates the need for motors or other drive mechanisms within the lifting chamber, resulting in a simpler structure.

[0027] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0028] The following describes in detail the overall structure, working principle, and technical effects of the lifting chamber and gantry-type fabric placing equipment provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0029] Please refer to Figure 1 This utility model provides a gantry-type concrete placing device 1000, which is applied to scenarios requiring efficient and automated concrete placing, such as the production of precast concrete components and large-scale infrastructure projects. For example, bridge precasting.

[0030] Please refer to Figure 1 In this embodiment, the gantry-type fabric placing equipment 1000 includes a gantry frame 500, a fabric placing trolley 200, a lifting support frame 400, a lifting device 300, and a lifting chamber 100. The fabric placing trolley 200 is movably mounted on the gantry frame 500 and can move along the length of the gantry frame 500. The lifting support frame 400 is located on one side of the top of the gantry frame 500 and connected to the gantry frame 500. The lifting device 300 is mounted on the lifting support frame 400 and connected to the lifting chamber 100, and the lifting device 300 can lift the lifting chamber 100 to a preset height.

[0031] This embodiment uses a lifting chamber 100 and lifting support components and lifting equipment 300 to efficiently transfer concrete from cement trucks to concrete placing vehicles 200.

[0032] Please refer to Figures 1 to 8 In this embodiment, the lifting chamber 100 includes a chamber body 110 and a chamber door 120. The chamber body 110 has a receiving cavity 111, an opening 112 at its top, and a discharge port 113 at its bottom. The chamber door 120 is movably mounted on the chamber body 110 and can automatically close under gravity. The fabric placing trolley 200 is provided with a drive unit 210. The chamber door 120 is provided with an opening part 125 corresponding to the drive unit 210. After the lifting chamber 100 is lifted to a preset height, as the fabric placing trolley 200 moves along the gantry frame 500 toward the bottom of the lifting chamber 100, the drive unit 210 can abut against the opening part 125, and the drive opening part 125 drives the chamber door 120 to open.

[0033] In this embodiment, the silo door 120 is movably installed on the silo body 110, and the silo door 120 can close under gravity, thus eliminating the need for an additional power source for closing the door, resulting in a simple structure and low failure rate. The silo door 120 is equipped with an opening part 125 corresponding to the drive unit 210 located on the concrete placing trolley 200. Thus, after the lifting silo 100 raises the concrete to a preset height, the concrete placing trolley 200 moves towards the bottom of the lifting silo 100, driving the drive unit 210 to move. The drive unit 210 pushes the opening part 125 to open the silo door 120. This eliminates the need for manual opening, increasing efficiency, and also eliminates the need for motors or other drive components in the lifting silo 100, further simplifying its structure. After the concrete placing trolley 200 moves away, the silo door 120 closes the discharge port 113 under gravity. The entire process requires no manual opening or closing of the silo door 120.

[0034] It should be noted that the lifting silo 100 is used for storing and transferring concrete. The lifting silo 100 can be made of different materials as needed. In this embodiment, the silo body 110 is mainly welded from high-strength steel plates. In other embodiments, alloy steel or wear-resistant liners can also be used to cope with different working conditions. The lifting silo 100 can be configured with different shapes as needed. In this embodiment, its main body is roughly funnel-shaped, smaller at the bottom and larger at the top.

[0035] Please refer to Figures 1 to 8 In this embodiment, a lifting frame 116 is fixedly installed on the top of the silo body 110 for reliable connection with the lifting device 300. A support frame 117 extending beyond the silo door 120 is fixedly installed at the bottom of the silo body 110. When parked on the ground, the support frame 117 bears the weight, effectively protecting the silo door 120 from damage.

[0036] It should also be noted that the silo door 120 is used to close the discharge port 113 and to open in a controlled manner for unloading. The silo door 120 can adopt different specific structures as needed.

[0037] In this embodiment, the door 120 includes a door body 121 and connecting lugs 122 disposed on both sides of the door body 121 along its length. The two connecting lugs 122 are rotatably connected to both sides of the storage body 110. The door body 121 and the connecting lugs 122 can be connected by welding or integral molding according to different needs and circumstances.

[0038] Please refer to Figures 1 to 9 In this embodiment, the silo door body 121 is arc-shaped. An arc-shaped plate 114 is correspondingly provided at the bottom of the silo body 110, and the discharge port 113 is located on the arc-shaped plate 114. In the closed state, the arc-shaped silo door body 121 covers the outside of the arc-shaped plate 114. This arc-shaped covering structure, compared to a flat fit, can form a more effective seal, preventing concrete slurry leakage.

[0039] Specifically, channel steel is welded to both ends of the outer side of the warehouse door body 121 in the width direction. The channel steel can enhance the mechanical strength of the warehouse door body 121, thereby improving its deformation problem.

[0040] Specifically, shaft seats 118 are installed on both sides of the compartment body 110; each of the two connecting lugs 122 is provided with a bearing seat 123, and a bearing 124 is installed inside the bearing seat 123; the shaft seat 118 is inserted into the inner ring of the bearing 124. This bearing 124 connection method makes the opening and closing of the compartment door 120 extremely smooth, with low resistance and long service life.

[0041] Furthermore, the opening part 125 is a boss 1251 provided on the side wall of the connecting lug 122. The driving part 210 is a lever 211 extending to the top plane of the fabric cart 200. The lever 211 corresponds to the boss 1251 in position and can convert the horizontal movement of the fabric cart 200 into the rotational movement of the door 120.

[0042] It should be noted that in other embodiments, the compartment door 120 may also adopt other structures such as a sliding type or a double-opening type. The connection between the connecting lug 122 and the compartment body 110 may also adopt a hinge or a pivot joint connection.

[0043] It should also be noted that the concrete placing trolley 200 is used to carry concrete and move on the gantry 500 for concrete placement operations. The concrete placing trolley 200 is movably mounted on the gantry 500 and can move along the length of the gantry 500. The concrete placing trolley 200 is provided with a drive unit 210, namely a lever 211, extending beyond its top. When the concrete placing trolley 200 moves below the lifting chamber 100, the lever 211 can interfere with the boss 1251 and push it to move.

[0044] Please refer to Figures 1 to 8 The lifting support frame 400 provides a stable mounting base for the lifting device 300. The lifting support frame 400 is located on one side of the top of the gantry 500 and is securely connected to the gantry 500 by high-strength bolts or welding. The lifting device 300 is used to lift and lower the lifting chamber 100. The lifting device 300 (such as an electric hoist or winch) is installed on the lifting support frame 400, and the lifting fixture at the lower end of its wire rope or chain is connected to the lifting frame 116 on the top of the chamber 110.

[0045] During operation, the lifting hoist 300 lifts the fully loaded concrete hopper 100 to a preset height. When it is necessary to replenish the concrete placing trolley 200, the trolley 200 moves directly below the lifting hopper 100. During the relative movement between the two, the lever 211 on the placing trolley 200 pushes the boss 1251 on the hopper door 120, forcing the hopper door 120 to rotate and open around the shaft seat 118 against gravity, and the concrete is discharged into the receiving hopper of the placing trolley 200 through the discharge port 113. After replenishment is completed, the placing trolley 200 moves away, the lever 211 separates from the boss 1251, and the hopper door 120 automatically resets and closes under gravity.

[0046] Please refer to Figures 1 to 8 Furthermore, the lifting chamber 100 also includes a linkage plate 130. The bottom of the chamber body 110 has two discharge ports 113, each with a corresponding arc-shaped plate 114. There are two chamber doors 120. Both chamber doors 120 are rotatably connected to the sides of the chamber body 110 via connecting lugs 122, and each corresponds to a discharge port 113. A recessed clearance space 115 is provided at the bottom of the chamber body 110 between the two chamber doors 120. The two chamber doors 120 are connected by the linkage plate 130.

[0047] This embodiment sets up two discharge ports 113 and two bin doors 120, and links the two bin doors 120 together through a linkage plate 130, so that the lifting bin 100 can quickly drop materials onto the material distribution vehicle 200.

[0048] Please refer to Figures 1 to 8 Furthermore, the boss 1251 includes a first segment 1251a and a second segment 1251b connected in sequence; the end of the first segment 1251a is connected to the connecting lug 122, and a retaining ring groove 1251c is provided between the first segment 1251a and the second segment 1251b; both ends of the linkage plate 130 are provided with hinge holes 131, and both ends of the linkage plate 130 are rotatably mounted on the first segment 1251a through the hinge holes 131; a retaining ring is provided in the retaining ring groove 1251c for axial positioning; and the second segment 1251b is used to cooperate with the lever block 211.

[0049] In this embodiment, the boss 1251 is set into two sections, which can realize the installation of the linkage plate 130 and also cooperate with the lever 211 on the fabric cart 200 to open the two compartment doors 120, thus reducing the number of parts.

[0050] In addition, a guide 140 is provided on the inner side of the silo body 110 corresponding to the clearance space 115. The guide 140 has two inclined guide surfaces 141 that are inclined to the two discharge ports 113. The guide 140 can prevent the silo body 110 from forming a horizontal plane, so that the concrete in the silo body 110 can flow to the discharge port 113.

[0051] Please refer to Figures 1 to 8 In this embodiment, the material guide 140 is formed in an inverted "V" shape, which allows the material to be guided from the middle to both sides, thus avoiding concrete residue.

[0052] Please refer to Figures 1 to 8 When the lever 211 of the concrete placing trolley 200 pushes the second section 1251b of the boss 1251 of one of the compartment doors 120, the compartment door 120 begins to rotate. Since the first section 1251a of its boss 1251 is connected to the boss 1251 of the other compartment door 120 through the linkage plate 130, this rotation will immediately force the other compartment door 120 to rotate and open synchronously through the linkage plate 130. The guide ramp 141 of the guide member 140 ensures that the concrete is smoothly guided to the two discharge ports 113. Therefore, this double compartment door 120 linkage structure has the effects of fast unloading speed, uniform unloading, and only one drive point is needed to control the synchronous operation of the two doors.

[0053] In summary, this embodiment movably mounts the silo door 120 to the silo body 110, allowing it to close under gravity. This eliminates the need for an additional power source for closing the door, resulting in a simple structure and low failure rate. The silo door 120 is equipped with an opening part 125 corresponding to the drive unit 210 located on the concrete placing trolley 200. When the lifting silo 100 raises the concrete to a preset height, the concrete placing trolley 200 moves towards the bottom of the lifting silo 100, driving the drive unit 210 to move. The drive unit 210 then pushes the opening part 125 to open the silo door 120. This eliminates the need for manual opening, increasing efficiency and eliminating the need for motors or other drive mechanisms in the lifting silo 100, thus simplifying its structure. After the concrete placing trolley 200 moves away, the silo door 120 closes the discharge port 113 under gravity. The entire process requires no manual opening or closing of the silo door 120.

[0054] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
