[0026] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the specific embodiments of the present invention in conjunction with the accompanying drawings of the embodiments of the present invention. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0027] In order to clearly illustrate the technical solution of the present invention, the following are defined: Figure 1 The front side, rear side, left side, right side, upper side, and lower side shown represent the front side, rear side, left side, right side, upper side, and lower side of the weight placement device.

[0028] like Figure 1 As shown, the present application discloses a weight placement device 100 for placing weights and weight accessories in single crystal furnace equipment. The weight placement device 100 includes a chassis 11, a lifting assembly 12, a locking assembly 13 and a tray 14. Among them, a guide wheel 111 is installed on the lower end face of the chassis 11, which serves as a bottom support and realizes the movement function of the weight placement device 100. Optionally, the guide wheel 111 can be configured as a universal wheel. The lifting assembly 12 is installed on the chassis 11 and is located on the upper surface of the bottom plate 11. The lifting assembly 12 can be extended and retracted in the height direction. The lifting assembly 12 realizes the lifting function of the weight placement device 100 and meets the height requirement of the weight placement device 100. The locking assembly 13 is configured to engage with the lifting assembly 12 when the lifting assembly 12 is at a set height. At this time, the locking assembly 13 is locked to fix the lifting assembly 12 at the set height. The tray 14 is located above the lifting assembly 12 and is fixedly connected to the lifting assembly 12, that is, the tray 14 is located on the side of the lifting assembly 12 away from the chassis 11, as shown in FIG. Figure 2As shown, the tray 14 is provided with a first accommodating portion 141, which has a through hole passing through two opposite end surfaces of the tray 14. The first accommodating portion 141 allows part of the weight to pass through the through hole and supports the weight in the height direction. Moreover, the first accommodating portion 141 also abuts against the weight in the horizontal direction, plays a limiting role on the weight, further fixes the weight, and avoids the weight placed on the tray 14 from moving and posing a safety hazard.

[0029] When in use, the weight placing device 100 is moved to the bottom of the weight, the lifting assembly 12 is adjusted, and the locking assembly 13 is locked when the lifting assembly 12 is at the set height, thereby fixing the height of the tray 14, and the weight placing device 100 is moved, and the first accommodating portion 141 on the tray 14 is aligned with the weight, and the weight is placed steadily in the first accommodating portion 141, and then the steel cable locking pin on the weight is removed, and the steel cable is taken out to complete the removal of the weight.

[0030] According to the above description, the weight placing device 100 can adjust the height position of the pallet 14 through the lifting assembly 12, place the weight on the first receiving portion position 141 of the pallet 14, and fix the weight to achieve safe operation during the weight placing process, and flexibly move the weight placing device 100 through the guide wheel 111 set on the chassis 11, combined with the fixing effect of the pallet 14 on the weight, to avoid personal injury and equipment damage during the weight handling operation, and achieve safe operation of the weight during the moving process.

[0031] like Figure 1 As shown, as an implementation, the tray 14 is further provided with a plurality of partitions 143, which surround and form a plurality of independent receiving slots 144, which can be used to accommodate accessories related to the weight. Furthermore, some of the partitions 143 provided on the tray 14 surround the through-hole formed in the first receiving portion 141, further isolating the weight and preventing burns.

[0032] As an implementation method, the upper surface of the pallet 14 is also covered with an isolation layer. The isolation layer is made of polyurethane material to achieve high temperature resistance. In addition, the isolation layer also avoids direct contact between the heavy hammer and the pallet, playing the role of metal isolation.

[0033] Furthermore, if Figure 3 As shown, a second accommodating portion 142 is also provided at the bottom of the tray 14. The second accommodating portion 142 is located directly below the first accommodating portion 141, and a disposal volume is formed around the second accommodating portion 142. The disposal volume is connected to the through hole. After the weight passes through the through hole, the disposal volume formed by the second accommodating portion 142 can be used to accommodate a part of the weight.

[0034] like Figure 4As shown, as an optional implementation, the structure formed by the combination of the first accommodating portion 141 and the second accommodating portion 142 has a stepped cross-section along the radial direction of the through hole, which can better fix the weight and prevent the weight from moving.

[0035] like Figure 5 and Figure 6 As shown, as an implementation, the lifting assembly 12 includes a connecting rod mechanism 121 (the connecting rod mechanism 121 includes multiple connecting rods, and two connecting rods are hinged) and a connecting rod driving mechanism 122. The two ends of the connecting rod mechanism 121 are respectively connected to the chassis 11 and the tray 14. One end of the connecting rod driving mechanism 122 is movably connected to the chassis 11, and the other end of the connecting rod driving mechanism 122 is movably connected to the connecting rod mechanism 121. The connecting rod driving mechanism 122 drives the connecting rod mechanism 121, thereby causing the connecting rod mechanism 121 to move in the height direction to adjust the height of the tray 14.

[0036] Specifically, the connecting rod mechanism 121 includes a first connecting portion 1211 and a second connecting portion 1212. The first connecting portion 1211 of the connecting rod mechanism 121 is hinged to the mounting portion on the left side of the chassis 11 via a rotating shaft. The connecting rod mechanism 121 is configured to move up and down with the mounting portion on the chassis 11 as a fixed point via the first connecting portion 1211. Figure 6 As shown, a first limiting guide rail 112 extending in the horizontal direction is provided on the upper end face of the chassis 11, and the second connecting portion 1212 of the connecting rod mechanism 121 is installed in the first limiting guide rail 112. The second connecting portion 1212 can be configured as a pulley, so that the connecting rod mechanism 121 can move horizontally along the first limiting guide rail 112 through the second connecting portion 1212.

[0037] When the connecting rod driving mechanism 122 is extended, the first connecting part 1211 of the connecting rod mechanism 121 rotates upward relative to the rotating shaft with the installation part on the chassis 11 as the fixed point, and the second connecting part 1212 of the connecting rod mechanism 121 moves along the first limiting guide rail 112 toward the direction close to the first connecting part 1211 under the action of the pulley, so that the connecting rod mechanism 121 in the compressed state is extended and the position of the tray 14 is raised; when the connecting rod driving mechanism 122 is retracted, the first connecting part 1211 of the connecting rod mechanism 121 rotates downward relative to the rotating shaft with the installation part on the chassis 11 as the fixed point, and the second connecting part 1212 of the connecting rod mechanism 121 moves along the first limiting guide rail 112 toward the direction away from the first connecting part 1211 under the action of the pulley, so that the connecting rod mechanism 121 in the extended state is compressed and the position of the tray 14 is lowered.

[0038] like Figure 6As shown, as an implementation method, the connecting rod mechanism 121 also includes a third connecting portion 1213 and a fourth connecting portion 1214. The third connecting portion 1213 of the connecting rod mechanism 121 is hinged to the mounting portion on the lower end surface of the left side of the tray 14. The connecting rod mechanism 121 is configured to move up and down with the mounting portion on the tray 14 as a fixed point through the third connecting portion 1213. A second position-limiting guide rail 113 extending in the horizontal direction is provided on the lower end surface of the tray 14. The fourth connecting portion 1214 of the connecting rod mechanism 121 is installed in the second position-limiting guide rail 113. The fourth connecting portion 1214 can be configured as a pulley, so that the connecting rod mechanism 121 can move horizontally along the second position-limiting guide rail 113 through the fourth connecting portion 1214.

[0039] As an implementation method, the locking assembly 13 includes a card slot installed on the tray 14 and / or the chassis 11. When the second connecting part 1212 and the fourth connecting part 1214 in the connecting rod mechanism 121 slide to the left until the lifting assembly 12 is at a set height, the second connecting part 1212 and the fourth connecting part 1214 are located in the card slot of the locking assembly 13, thereby fixing the lifting assembly 12 and then fixing the height of the tray 14, avoiding changes in the position of the tray 14 when using the heavy hammer placement device 100.

[0040] As an optional implementation, the lifting assembly 12 may include a telescopic electric cylinder, the two ends of which are fixedly connected to the chassis 11 and the tray 14 respectively, and the telescopic electric cylinder extends in the height direction to adjust the height position of the tray 14.

[0041] According to the above description, the utility model provides a weight placing device 100, which can adjust the height position of the tray 14 through the lifting component 12, and fix the weight on the tray 14 to avoid safety hazards such as high temperature burns or weight slipping when manually carrying the weight, thereby achieving safe operation during the weight placement process, and through the guide wheels 111 set on the chassis 11, combined with the fixing effect of the tray 14 on the weight, achieving safe operation of the weight during the moving process.

[0042] Although the preferred embodiments of the present application have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the application as disclosed in the accompanying claims.

[0043] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims appended to this application.
