Description

Technical Field

[0001] The utility model belongs to the field of ray detection, in particular to a conveying device for a lead house. Background Art

[0002] Existing ray detection equipment includes a lead protection house and a ray detection device assembled inside the lead protection house. Workpieces need to be loaded into the lead house manually or by a robot. Especially when detecting large workpieces, due to the narrow space inside the lead house, it is very unfavorable for taking and placing workpieces. The ray detection mechanism is used to comprehensively detect various workpieces. Therefore, a conveying device needs to be designed to realize the reciprocating conveyance of workpieces for rapid detection.

[0003] However, for some heavy workpieces, it is required to move the detection table for ray detection to the outside of the lead protection house for hoisting operations. Since there is a necessary protective lead door in the middle of the lead protection house, the track of the conveying device needs to be disconnected, resulting in that the traditional conveying device is difficult to directly enter and exit the lead house, which limits the ability of the workpieces to be detected to freely pass in and out of the lead house. Summary of the Utility Model

[0004] In order to overcome the above technical defects, the utility model provides a conveying device for a lead house to solve the problems involved in the background art.

[0014] Two rows of limiting rollers are installed in the receiving notch, and the two rows of limiting rollers are respectively located on the upper and lower sides of the linear guide rail.

[0015] Preferably or optionally, the diameters of the limiting rollers at both ends are smaller than those of the limiting rollers at other positions.

[0016] Preferably or optionally, the transmission track further includes: a base suitable for installing the linear guide rail and the rack, and a plurality of liftable feet fixedly installed at the bottom of the base.

[0030] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0031] Refer to the attached Figures 1 to 4 , A conveying device for a lead house, comprising: two transmission tracks 100 and a transmission trolley 300.

[0032] Among them, the two transmission tracks 100 are respectively arranged inside and outside the lead-lined protective house, and the two transmission tracks 100 are arranged at intervals to form a predetermined gap 200 allowing the lead door to pass through, so as to open and close the lead door without hindrance; each of the transmission tracks 100 includes two linearly arranged parallel guide rails 110 and a rack 120 arranged parallel to the linear guide rails 110; the transmission trolley 300 includes a frame 310 whose length is at least greater than the predetermined gap 200, two long strip-shaped sliding members 320 formed on both sides of the bottom of the frame 310 and respectively clamped on the two linear guide rails 110, two driving gears 330 respectively arranged at both ends of the frame 310 and meshed with the rack 120, and a first driving source 340 drivingly connected to the driving gear 330.

[0033] In this embodiment, long-strip-shaped sliding members 320 are assembled on both sides of the bottom of the frame 310 and are embedded in the linear guide rails 110 on the inner and outer sides, ensuring the smooth sliding of the transfer trolley 300 on the track. Moreover, a set of driving gears 330 is equipped at each end of the transfer trolley 300 to ensure that at least one driving gear 330 is in close meshing with the rack 120, which serves as the power interface for the forward and backward movement of the transfer trolley 300, thereby driving the transfer trolley 300 to achieve precise and controllable reciprocating movement on the track. Without damaging the integrity of the lead chamber's protection, the efficient and safe transportation of workpieces from the outside to the inside is realized, greatly optimizing the ray detection process of the workpieces.

[0034] In a further embodiment, the first driving source 340 drives the two driving gears 330 to always maintain the same rotation speed and rotation direction, thereby driving the transfer trolley 300 to achieve precise and controllable reciprocating movement on the track. Two exemplary structures are given in this embodiment. In the first structure, the first driving source 340 includes: a servo motor, and two transmission mechanisms connected to the output end of the servo motor and respectively connected to the two driving gears 330. In the second structure, the first driving source 340 includes two servo motors respectively drivingly connected to the driving gears 330.

[0035] In a further embodiment, the sliding member 320 includes: a mounting seat 321, a receiving notch 322, and two rows of limiting rollers 323. The mounting seat 321 is of a long-strip-shaped structure and is fixedly connected to the bottom of the frame 310; the receiving notch 322 is formed on the side of the mounting seat 321, such that a part of the mounting seat 321 is embedded in the linear guide rail 110; the two rows of limiting rollers 323 are installed in the receiving notch 322, and the two rows of limiting rollers 323 are respectively located on the upper and lower sides of the linear guide rail 110. By respectively positioning the two rows of limiting rollers 323 on the upper and lower sides of the linear guide rail 110, when the transfer trolley 300 passes through the predetermined gap 200, even if some of the limiting rollers 323 are suspended and lose the support of the linear guide rail 110, the remaining limiting rollers 323 are clamped on the linear guide rail 110 and can still closely adhere to the linear guide rail 110, maintaining the necessary supporting force and guiding function, which can ensure the stability and smooth movement of the moving transfer trolley 300.

[0036] In a further embodiment, the diameter of the limiting rollers 323 at both ends is smaller than that of the limiting rollers 323 at other positions. When the transfer trolley 300 needs to smoothly transition from one section of the track to another section, it can enable the two rows of limiting rollers 323 to accurately engage with another linear guide rail 110, reducing the risk of dislocation and ensuring the precise docking of the transport transfer trolley 300 and the linear guide rail 110.

[0037] In a further embodiment, the transmission track 100 further includes: a base 130 adapted to mount the linear guide 110 and the rack 120, and a plurality of liftable feet 140 fixedly installed at the bottom of the base 130. Since the heights inside and outside the lead shielding room are not the same, the linear guide 110 can be located on the same horizontal plane through the liftable brackets, reducing the risk of misalignment and ensuring the precise docking of the transfer cart 300 and the linear guide 110. Additionally, a limiting member 150 is provided at one end of the base 130 away from the predetermined gap 200. This can prevent the transfer cart 300 from exceeding the predetermined operating range in case of an accident, such as excessive movement of the transfer cart 300 caused by an operation error or an abnormal power system, effectively avoiding equipment damage or safety accidents.

[0038] In a further embodiment, a drag chain 400 is provided on one side of the base 130 of at least one transmission track 100. The drag chain 400 houses the power cables, signal cables, and control cables required for the transfer cart 300, avoiding the cables from being pulled, squeezed, or worn during the movement of the transfer cart 300, thereby extending the service life of the electrical circuits and reducing the maintenance cost.

[0039] In a further embodiment, a rotating platform 350 is further provided on the upper surface of the frame 310. The workpiece can be rotated 360 degrees or within a specific angular range through the rotating platform 350, which greatly expands the coverage range of the ray detection, ensures the comprehensive detection of all surfaces and angles of the workpiece, improves the detection efficiency, and increases the detection reliability.

[0040] It should be further noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention does not further describe various possible combination methods.
