Description

Technical Field

[0001] This utility model relates to the field of anchor drilling rig technology, and specifically to a resin cartridge for anchor drilling rigs. Background Technology

[0002] Rock bolt support is a crucial support method in roadway engineering such as coal mines and tunnels. Resin rock bolts are widely used due to their high anchoring force and reliability. During the construction of resin rock bolts, a resin cartridge hopper equipped with a rock bolt drilling rig is typically used to store and transport the resin cartridges. In existing technology, the working principle of the resin cartridge hopper is as follows: a motor drives the main shaft to rotate, and a pushing mechanism (such as a paddle or spiral blade) fixed on the main shaft pushes the resin cartridges one by one from the hopper to the discharge port, ultimately completing the filling.

[0003] This traditional conveying method has a significant technical drawback in practical applications: motion interference and jamming between the compartment door and the main shaft. Specifically, to control the conveying of resin cartridges and prevent them from scattering, the cartridge compartment is usually equipped with an openable and closable door. When the door is closed, if the door is in close contact with the main shaft, the rotating main shaft will experience frictional interference with the door. If there is a gap between the door and the main shaft, although the friction problem between the main shaft and the door is temporarily solved, the outer packaging of the resin cartridges may break due to compression and friction during the conveying process. The resulting plastic debris and dust will mix and accumulate in the narrow gap between the main shaft and the door. These accumulations will further increase the frictional resistance, making jamming more frequent and severe.

[0004] The aforementioned friction and jamming issues severely impact the smoothness and stability of resin cartridge delivery. This directly manifests as reduced delivery efficiency, forcing frequent interruptions of anchor bolt support operations to address malfunctions, and significantly slowing down the overall tunnel excavation progress. Unstable cartridge delivery may lead to filling failures or misalignment of the cartridge within the borehole, affecting the thorough mixing and curing of the resin with the anchor bolt, thereby reducing anchoring force and posing a potential threat to tunnel support quality and safe production.

They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of the invention, should still fall within the scope of the technical content disclosed herein.

[0022] like Figures 1-4 As shown, this utility model provides a resin cartridge chamber 100 for anchor drilling rigs, including a chamber body 110, a chamber door 120, and a main shaft 130. The main shaft 130 is disposed inside the chamber body 110, and the chamber door 120 is connected to the chamber body 110. A bearing assembly 170 is also connected to the chamber body 110. When the chamber door 120 is closed, the bearing assembly 170 is positioned between the main shaft 130 and the door hole 122 of the chamber door 120. The inner side of the bearing assembly 170 is in contact with the bearing 173, and the outer side of the bearing assembly 170 is in contact with the inner peripheral wall of the door hole 122. This eliminates frictional interference between the main shaft 130 and the chamber door 120, and also eliminates the gap between the chamber door 120 and the main shaft 130, thus preventing frictional interference caused by dust and debris entering the gap.

[0023] It should be noted that, Figure 3 The central aperture 122 is not fitted to the bearing assembly 170; this is to demonstrate the existence of the aperture 122. In reality, the inner peripheral wall of the aperture 122 is tightly fitted to the outer peripheral wall of the bearing assembly 170. It should also be noted that the inner and outer sides of the bearing assembly 170 mentioned above are with reference to the axis of the bearing assembly; the inner side refers to the inner peripheral wall, and the outer side refers to the outer peripheral wall.

[0024] When the aforementioned door 120 is opened, the fixing member 160 is first released from the fixing of the door 120 and the compartment body 110. Then, the door 120 is moved away from the compartment body 110, so that the door hole 122 is disengaged from the bearing assembly 170. Finally, the door 120 is rotated to open the compartment. When the aforementioned door 120 is closed, the door 120 is first rotated to align the door 120 with the opening end of the compartment body 110. Then, the door 120 is moved closer to the compartment body 110, so that the end of the door 120 fits against the compartment body 110, closing the compartment body 110. At the same time, the door hole 122 fits against the outside of the bearing assembly 170. Finally, the door 120 is fixed to the compartment body 110 by the fixing member 160. The door 120 is opened and closed by translation and rotation, so that the door hole 122 of the door 120 can fit against the outside of the bearing assembly 170, eliminating gaps and fundamentally eliminating the possibility of dust and debris clogging the gaps.

[0025] As one embodiment of the aforementioned door 120's sliding and rotating opening and closing, a pivot 121 is provided on one side of the door 120. The pivot 121 can be fixedly connected to the door 120 or rotatably connected. The pivot 121 is rotatably disposed within the support member 140, allowing the door 120 to rotate open or close around the pivot 121. Simultaneously, the support member 140 also supports the weight of the door 120. The support member 140 is connected to the storage body 110 via a translation member 150. This translation member 150 allows the support member 140 to move closer to or further away from the storage body 110, thereby causing the door 120 mounted on the support member 140 to move closer to or further away from the storage body 110.

[0026] Furthermore, the support member 140 is provided with a shaft groove 141 that matches the rotating shaft 121 on the door 120, and the rotating shaft 121 is rotatably disposed in the shaft groove 141. The support member 140 is disposed at the lower or upper part of the compartment body 110, and the upper end of the shaft groove 141 is open to facilitate placing the rotating shaft 121 in the shaft groove 141 or removing the rotating shaft 121 from the shaft groove 141. At the same time, due to the weight of the door 120 itself, even if the upper end of the shaft groove 141 is open, the rotating shaft 121 cannot disengage from the opening of the shaft groove 141.

[0027] In one embodiment, the translation member 150 is configured as a plug rod, and the support member 140 is fixedly disposed at the end of the plug rod. The chamber body 110 is provided with a plug hole 111, and the plug rod is slidably engaged with the plug hole 111. By pushing or pulling the plug rod, the support member 140 can be translated to move closer to or away from the chamber body 110. Optionally, the translation member 150 is configured as a telescopic rod (not shown in the figure), and the support member 140 is fixedly disposed at the end of the telescopic rod, and the other end of the telescopic rod is fixedly disposed on the chamber body 110, so that the support member 140 can be translated to move closer to or away from the chamber body 110.

[0028] Preferably, two sets of the aforementioned translation member 150 and support member 140 are provided to ensure the stability of the door 120 during the opening and closing process. Figure 2 and Figure 3 As shown, two sets of translation components 150 and support components 140 are symmetrically arranged at the lower part of the compartment body 110.

[0029] In one embodiment of fixing the door 120 to the body 110, the fastener 160 can be a bolt, which directly fixes the door 120 to the body 110. In another embodiment, since the bearing assembly 170 is in contact with the door hole 122 of the door 120 when the door 120 is closed, the door 120 only has the freedom to translate away from the body 110. Therefore, the position between the door 120 and the body 110 can be constrained by snap-fit ​​or plug-in connection, preventing the door 120 from moving away from the body 110, thereby achieving the purpose of fixing the door 120.

[0030] In one embodiment, the bearing assembly 170 includes a bushing 171, a sleeve 172, and a bearing 173.

[0031] The bushing 171 is fixedly connected to the end of the main shaft 130, ensuring a tight fit between the inner side of the bearing assembly 170 and the main shaft 130, preventing gaps. Preferably, the end of the main shaft 130 has a threaded hole, and the corresponding position of the bushing 171 has a through hole. The bushing 171 is fixedly installed on the main shaft 130 by a first bolt 174, and a washer 175 is provided between the first bolt 174 and the bushing 171.

[0032] The sleeve 172 is fixedly connected to the silo body 110 via the mounting plate 180. When the silo door 120 is closed, the outer peripheral wall of the sleeve 172 fits against the inner peripheral wall of the door hole 122 of the silo door 120, preventing gaps from forming. Specifically, the mounting plate 180 is fixedly installed on the silo body 110 via the second bolt 181, and the sleeve 172 is welded and fixed to the mounting plate 180.

[0033] The bearing 173 is disposed between the bushing 171 and the sleeve 172, so that the bushing 171 can rotate freely relative to the sleeve 172. The bearing 173 is preferably configured as a lubrication-free bearing 173.

[0034] In one embodiment, the door 120 is provided with an observation port 123, and the observation port 123 is provided with a transparent window 190, which facilitates observation of the working conditions inside the compartment 110 while ensuring the overall airtightness of the door 120. Specifically, the transparent window 190 is located on the side of the observation port 123 away from the compartment 110, which facilitates the installation and replacement of the transparent window 190. The transparent window 190 can be made of transparent plastic material, which ensures visibility while reducing the weight of the door 120.

[0035] Furthermore, multiple observation ports 123 are evenly arranged around the door openings 122 of the storage door 120, which means that the storage door 120 is set as a frame structure with a large area of ​​openwork at multiple points, which increases the viewing area and further reduces the weight of the storage door 120; a single transparent window 190 is used to cover the side of the storage door 120 away from the storage body 110, and multiple observation ports 123 are installed at one time, saving the installation time of the transparent window 190; and the transparent window 190 is provided with a hole for the bearing assembly 170 to pass through, the position of which corresponds to the door opening 122.

[0036] In one embodiment, an end plate 112 is provided at the end of the silo body 110. The aforementioned components such as the mounting plate 180 and the translation component 150, which are mounted on the silo body 110, are actually all mounted on the end plate 112 at the end of the silo body 110.

[0037] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
