Description

Auxiliary marking system and construction machinery production line Technical Field

[0001] This invention relates to the field of auxiliary marking technology, specifically to an auxiliary marking system and an engineering machinery production line. Background Technology

[0002] The turntable of a truck crane is generally marked using a coordinate measuring machine (CMM). Before marking, the placement of the structure to be marked needs to be adjusted. Currently, the method for adjusting the placement of the structure is as follows: the crane lifts the structure and places it on a center pin. The center pin is adjusted to level the structure front to back. Then, the crane is used to lift and adjust the structure until it is parallel to the CMM's track. However, the structure to be marked is large and heavy, posing safety hazards when adjusting it using a crane. Furthermore, adjusting the center pin is necessary to ensure the correct placement of the structure during the marking process. Summary of the Invention

[0003] In view of at least one of the above-mentioned defects or deficiencies in the prior art, the present invention provides an auxiliary marking system and an engineering machinery production line, which can facilitate the adjustment of the placement position of the structure to be marked, and can meet the placement requirements of the structure to be marked without frequently lifting it, thereby making the process of adjusting the structure to be marked time-saving and labor-saving, while improving the safety of operation.

[0004] To achieve the above objectives, the first aspect of the present invention provides an auxiliary marking system, comprising:

[0005] A slewing support assembly is used to support one end of the structure to be scribed in the lateral direction; and

[0006] A circumferential support assembly is provided at intervals on the radially outer side of the rotary support assembly and is used to support the other end of the structure to be scribed in the transverse direction;

[0007] The structure to be marked can be positioned vertically by the joint support of the rotary support assembly and the circumferential support assembly, and can be positioned laterally by the rotary motion of the rotary support assembly and the circumferential support assembly moving around the rotary support assembly.

[0008] Optionally, the ring-moving support assembly includes a base, a lifting support mechanism disposed on the top of the base and capable of vertical movement, and a moving mechanism disposed at the bottom of the base.

[0009] Optionally, the lifting support mechanism includes:

[0010] A fixing sleeve assembly includes a fixing sleeve fixedly disposed on the top of the base and a limiting key disposed on the inner peripheral wall of the fixing sleeve; and

[0011] A screw assembly includes a rotating sleeve, a screw, and a support cap. The rotating sleeve includes a sleeve portion rotatably fitted inside a fixed sleeve and a turntable portion extending radially from one end of the sleeve portion and abutting against one end of the fixed sleeve. The screw is fitted inside the rotating sleeve and forms a threaded engagement with the rotating sleeve. A limiting groove extending axially is formed on the peripheral wall of the screw. A limiting key is engaged with the limiting groove and forms a sliding engagement with the limiting groove. The support cap is sleeved on one end of the screw.

[0012] Optionally, the screw assembly includes a drive handle fixedly connected to the turntable portion and used to drive the sleeve portion to rotate within the fixed sleeve.

[0013] Optionally, the transfer mechanism includes multiple lockable casters with self-locking function.

[0014] Optionally, the base includes a base top plate, a base bottom plate arranged parallel to and spaced apart from the base top plate, and a plurality of base rods connecting the base top plate and the base bottom plate. The lifting support mechanism is disposed on the base top plate, and the moving mechanism is disposed on the base bottom plate.

[0015] Optionally, the slewing support assembly includes a slewing platform and a plurality of equal-height support members spaced apart on the platform surface, with the tops of the plurality of equal-height support members being at the same horizontal height.

[0016] Optionally, the slewing support assembly is provided with a slewing power device for generating slewing rotational force; and / or, the circumferential support assembly is provided with a circumferential force device for generating circumferential kinetic force.

[0017] Optionally, one of the slewing support assembly and the annular support assembly is configured as a human-powered mechanism that generates power through manual force application, and the other is configured as a driven mechanism.

[0018] A second aspect of the present invention provides an engineering machinery production line, which includes the above-described auxiliary marking system.

[0019] The marking auxiliary system of this invention is used in the production line of construction machinery such as truck crane turntables. Before marking the structure to be marked, the overhead crane lifts the structure, placing one end on the slewing support assembly and the other end on the circumferential support assembly. The vertical positioning of the structure is achieved through the joint support of the slewing and circumferential support assemblies. The lateral positioning of the structure is achieved through the rotational movement of the slewing support assembly and the movement of the circumferential support assembly around the slewing support assembly. Compared with the prior art, it makes adjusting the placement of the structure more convenient, eliminating the need for frequent lifting of the structure and adjustment with a center pin, thus meeting the placement requirements. This makes the adjustment process time-saving, labor-saving, and safer, thereby improving the production efficiency of the production line of construction machinery such as truck crane turntables.

[0037] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0039] In the embodiments of the present invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used to describe the relative positional relationships of the components in relation to the directions shown in the accompanying drawings or in relation to the vertical, perpendicular, or gravitational directions.

[0040] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0041] Referring to Figures 1 to 3, a first exemplary embodiment of the present invention provides an auxiliary marking system, which includes a rotary support assembly 1 and a circumferential support assembly 2. Specifically, the rotary support assembly 1 is used to support one end of the structure to be marked along the transverse direction. The circumferential support assembly 2 is arranged radially outward from the rotary support assembly 1 and is used to support the other end of the structure to be marked along the transverse direction.

[0042] The structure to be marked can be positioned vertically by the joint support of the slewing support assembly 1 and the circumferential support assembly 2, and can be positioned laterally by the slewing motion of the slewing support assembly 1 and the circumferential support assembly 2 moving around the slewing support assembly 1, thereby completing the position adjustment of the structure to be marked.

[0043] By setting up the above structure, before marking the structure to be marked, a crane lifts the structure to be marked, placing one end on the slewing support assembly 1 and the other end on the circumferential support assembly 2. The vertical positioning of the structure is achieved through the combined support of the slewing support assembly 1 and the circumferential support assembly 2. The lateral positioning of the structure is achieved through the rotational movement of the slewing support assembly 1 and the movement of the circumferential support assembly 2 around the slewing support assembly 1. Compared to existing technologies, the marking auxiliary system of this exemplary embodiment facilitates the adjustment of the placement of the structure to be marked, eliminating the need for frequent lifting of the structure and adjustment with a center pin, thus meeting the placement requirements of the structure. This makes the adjustment process time-saving and labor-saving, while also improving operational safety. Furthermore, this auxiliary marking system is applicable to different models of structures to be marked, demonstrating strong versatility.

[0044] As shown in Figure 2, the ring-shift support assembly 2 includes a base 21, a lifting support mechanism 22, and a moving mechanism 23. The base 21 serves as the supporting component of the ring-shift support assembly 2, supporting the lifting support mechanism 22 and connecting the lifting support mechanism 22 and the moving mechanism 23 to jointly form the ring-shift support assembly 2. The lifting support mechanism 22 is located at the top of the base 21 and can move up and down. Specifically, the lifting support mechanism 22 is mainly used to support the structure to be marked, and its vertical positioning is adjusted by lifting and moving. The moving mechanism 23 is located at the bottom of the base 21 and serves as the moving component of the ring-shift support assembly 2, enabling the ring-shift support assembly 2 to move around the rotary support assembly 1. It also facilitates the handling of the ring-shift support assembly 2 during use.

[0045] As shown in Figure 3, the lifting support mechanism 22 includes a fixed sleeve assembly 221 and a screw assembly 222. The fixed sleeve assembly 221 includes a fixed sleeve 221a and a limiting key 221b. Specifically, the fixed sleeve 221a is fixedly disposed on the top of the base 21 and is fixedly connected to the top of the base 21, and is used to connect with the rotating sleeve 222a. The limiting key 221b is disposed on the inner peripheral wall of the fixed sleeve 221a and is used to limit the movement direction of the screw 222b.

[0046] The screw assembly 222 includes a rotating sleeve 222a, a screw 222b, and a support cap 222c. The rotating sleeve 222a includes a sleeve portion and a turntable portion. Specifically, the sleeve portion is rotatably fitted inside the fixed sleeve 221a, and the turntable portion extends radially from one end of the sleeve portion and is limited and abuts against one end of the fixed sleeve 221a.

[0047] The screw 222b is fitted inside the rotating sleeve 222a and forms a threaded engagement with the rotating sleeve 222a. A limiting groove 222d extending axially is formed on the peripheral wall of the screw 222b. A limiting key 221b is inserted into the limiting groove 222d and forms a sliding engagement with the limiting groove 222d. This configuration allows the screw 222b to move only up and down. A support cap 222c is fitted over one end of the screw 222b. The support cap 222c supports the structure to be scribed, which is placed at one end of the annular support assembly 2 and abuts against the structure to be scribed.

[0048] By setting the above structure, in use, one end of the structure to be marked is placed on the support cap 222c, and the turntable is rotated, causing the screw 222b, which forms a threaded engagement with the rotating sleeve 222a, to move. Due to the setting of the limiting key 221b and the limiting groove 222d, the movement of the screw 222b is limited, so that the screw 222b can only move up and down, thereby realizing the lifting and lowering movement of the lifting support mechanism 22, thus completing the vertical positioning of the structure to be marked. Of course, the lifting and lowering movement of the lifting support mechanism 22 can also be realized by means of hydraulic cylinders or pneumatic cylinders, etc., and this exemplary embodiment does not limit this.

[0049] Furthermore, the screw assembly 222 includes a drive handle 222e, which is fixedly connected to the turntable and used to drive the sleeve portion to rotate within the fixed sleeve 221a. Specifically, by manually pushing the drive handle 222e, the turntable portion rotates, causing the sleeve portion to rotate within the fixed sleeve 221a, thereby allowing the screw 222b to move vertically. Of course, other power devices can also be used to drive the drive handle 222e, as long as power can be provided to the drive handle 222e to complete the rotation of the turntable portion and thus drive the screw 222b to rise and fall. This exemplary embodiment does not limit this.

[0050] Furthermore, the transfer mechanism 23 includes multiple locking casters 231 with a self-locking function. With this configuration, when the annular support assembly 2 needs to be moved, it can be moved using the multiple locking casters 231. When the annular support assembly 2 reaches the desired position, the self-locking function of the locking casters 231 locks it in place, thus fixing the annular support assembly 2 in the required position. Of course, the transfer mechanism 23 can also be other movable structures, as long as the structure satisfies the requirement of both allowing the annular support assembly 2 to move and fixing its position.

[0051] As shown in Figure 2, the base 21 includes a base top plate 211, a base bottom plate 212 arranged parallel to and spaced apart from the base top plate 211, and multiple base rods 213 connecting the base top plate 211 and the base bottom plate 212. A lifting support mechanism 22 is installed on the base top plate 211, and a moving mechanism 23 is installed on the base bottom plate 212. This configuration results in a simple overall structure for the base 21, while still fulfilling the required supporting and connecting functions. Furthermore, the base 21 is lightweight, making it easy to move during use. Additionally, the base 21 is made from readily available materials, resulting in low cost.

[0052] As shown in Figure 1, the slewing support assembly 1 includes a slewing platform 11, multiple equal-height support members 12, and a slewing support base 13. The slewing platform 11 can rotate relative to the slewing support base 13, thereby enabling the slewing support assembly 1 to perform slewing motion and complete the lateral positioning of the structure to be scribed. The multiple equal-height support members 12 are arranged at intervals on the platform of the slewing platform 11, and the tops of the multiple equal-height support members 12 are set at the same horizontal height. This arrangement ensures that when the structure to be scribed is placed on the slewing support assembly 1, it can maintain the same horizontal height, thereby completing the vertical positioning of the structure to be scribed without the need for repeated adjustments.

[0053] In this embodiment, the lateral positioning of the structure to be marked is accomplished by the rotational movement of the rotary support assembly 1 and the movement of the circumferential support assembly 2 around the rotary support assembly 1.

[0054] One approach is to include a rotary power device in the rotary support assembly 1 to generate rotary force. This device provides rotary power to the rotary support assembly 1, causing it to rotate and thus driving the circumferential support assembly 2 to move around it, thereby completing the horizontal positioning of the structure to be marked. Alternatively, the circumferential support assembly 2 can be equipped with a circumferential force device to generate circumferential force. This device provides circumferential force to the circumferential support assembly 2, causing it to move around the rotary support assembly 1. The weight of the structure to be marked then drives the rotary support assembly 1 to move as well, thus positioning the structure laterally. Alternatively, both the slewing support assembly 1 and the circumferential support assembly 2 can be equipped with power units to provide power for the horizontal movement of the marking auxiliary system. In use, the power units on the slewing support assembly 1 and the circumferential support assembly 2 can be driven simultaneously, so that the slewing support assembly 1 and the circumferential support assembly 2 can move in sync, thereby completing the lateral positioning of the structure to be marked.

[0055] In addition to providing power to the auxiliary marking system through a power unit, power can also be provided manually. Specifically, one of the slewing support assembly 1 and the circumferential support assembly 2 is configured as a manual mechanism that generates power through manual force, while the other is configured as a driven mechanism. That is, when power is generated by manual force on the circumferential support assembly 2, its circumferential movement will drive the slewing support assembly 1 to move, thereby completing the lateral positioning of the structure to be marked. The reverse is also true.

[0056] A second exemplary embodiment of the present invention provides an engineering machinery production line, which includes the aforementioned auxiliary marking system. The engineering machinery production line can be a production line for a truck crane turntable. For example, in the production of a truck crane turntable, this exemplary embodiment uses a crane to position the structure to be marked. First, a crane places the structure to be marked onto the auxiliary marking system. Through the combined action of the slewing support assembly 1 and the circumferential support assembly 2 of the auxiliary marking system, the vertical and lateral positioning of the structure to be marked is completed, thereby determining the placement position of the structure to be marked. The auxiliary marking system of this exemplary embodiment allows for position adjustment of the structure to be marked without frequent lifting of the structure or adjustment with a center pin, saving time and effort while improving operational safety, thus increasing the production efficiency of the truck crane turntable production line. Of course, the engineering machinery production line can also be other production lines that require marking of parts of the engineering machinery structure; this exemplary embodiment does not limit this.

[0057] The optional embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the specific details in the above embodiments. Within the scope of the technical concept of the embodiments of the present invention, various simple modifications can be made to the technical solutions of the embodiments of the present invention, and these simple modifications all fall within the protection scope of the embodiments of the present invention.

[0058] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the embodiments of the present invention will not describe the various possible combinations separately.

[0059] Furthermore, various different implementations of the present invention can be combined arbitrarily, as long as they do not violate the spirit of the present invention, they should also be regarded as the content disclosed in the present invention.
