Description

Technical Field

[0001] The utility model relates to the technical field of stackers, in particular to a stacker traveling device that can be quickly maintained. Background Art

[0002] Stackers are common equipment in modern logistics and warehousing. The running wheels at the bottom of stackers are prone to wear and tear during operation, requiring frequent maintenance. In recent years, the industry has proposed a wheel box structure to simplify the assembly, removal, and maintenance of the running wheels. However, these common wheel box structures have the following drawbacks: 1. Existing wheel box installation methods cannot adjust the axial position of the running wheels to ensure optimal alignment with the guide rails; 2. The wheel box is subject to significant radial loads during operation, making it difficult to prevent radial misalignment using traditional installation methods; and 3. The motor's requirements for vibration and torsion resistance cannot be met during operation. Utility Model Content

[0003] The purpose of the utility model is to provide a stacker crane running device that can be quickly maintained in response to the above-mentioned problems, and to propose a stacker crane running device with an easily disassembled wheel box, which has good radial positioning, shock absorption and anti-torsion functions, and the wheel box can be fine-tuned axially to fit the track.

[0004] The technical solution of the utility model is as follows:

[0005] A stacker crane travel device that can be quickly maintained includes an end head assembly and a running wheel box. The running wheel box includes a wheel box shell as a main frame. Bearings are provided on both sides of the wheel box shell. The wheel axle passes through the bearings and the running wheel and is fixed by an end cover I, a shaft sleeve I and a shaft sleeve II. A pin hole is provided on the wheel box shell and is aligned with the pin hole provided on the end head assembly. The pin hole is fixed by a pin shaft and an end cover II. At least two adjusting screws II and at least two adjusting nuts II are provided on both sides of the end head assembly. The adjusting screws II and adjusting nuts II fix the running wheel box from both sides.

[0006] Furthermore, the method further includes a running motor, which is connected to the wheel axle of the running wheel box, and the running motor is set on the anti-torsion bracket through screws.

[0007] Furthermore, two waist-shaped holes are provided at the bottom of the end head assembly, through which the guide wheel assembly passes and is fixed by the nut provided with the guide wheel assembly; an adjusting screw I is provided on the side of the end head assembly to support the guide wheel assembly, and the adjusting screw I is fixed by the adjusting nut I, so that the guide wheel assembly clamps the track.

[0008] Furthermore, the pin hole is tightened by a screw, a spring washer and a flat washer.

[0009] Furthermore, the end head assembly is fixedly arranged at the bottom of the stacker, a bracket is provided on the end head assembly, a threaded pull rod is provided on the bracket, a spherical bearing is provided on the top of the pull rod, and the pull rod and the spherical bearing are fastened by a nut.

[0010] Furthermore, a shock-absorbing pad is provided between the pull rod and the end assembly.

[0011] Furthermore, the joint bearing and the anti-torsion bracket with the rotating shaft form a shaft hole match, and the traveling motor is installed on the anti-torsion bracket by screws.

[0012] Compared with the existing technology, the beneficial effects of the present invention are:

[0013] 1. A stacker crane travel device that allows for quick maintenance. Multiple pairs of long screws are installed on either side of the stacker crane's base structure to support the wheel box and restrict its axial movement. During assembly, the wheel box can be placed in the optimal position on the track before tightening the bolts to adjust the wheel box's axial position.

[0014] 2. A stacker crane travel device that allows for quick maintenance. To prevent radial misalignment of the wheel box, a pair of pins are used as a radial positioning mechanism for the wheel box, limiting radial movement relative to the stacker crane's base structure. The travel motor is mounted on the stacker crane base via a torsion-resistant bracket with shock-absorbing pads, rather than being directly connected to the stacker crane via a fixed torsion-resistant support plate. This ensures high stability and low noise during operation.

[0015] 3. A stacker crane travel device that can be quickly maintained. Guide wheels with adjustable spacing are set at the bottom of the travel device to further ensure that the stacker crane travel device fits well with the track. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0022] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0023] See also Figure 1-4 , a stacker crane travel device that can be quickly maintained, such as Figure 1 、 Figure 2 As shown, the end assembly 1 is fixed to the bottom of the stacker. The bracket installed on it is equipped with a threaded pull rod 5. The top of the pull rod 5 is equipped with a spherical bearing 2, which is fastened with nuts 6. A shock-absorbing pad 7 is also installed between the pull rod 5 and the end assembly 1. The spherical bearing 2 forms a shaft hole with an anti-torsion bracket 3 with a rotating shaft. The travel motor 4 can be installed on the anti-torsion bracket 3 with screws.

[0024] like Figure 2 As shown, the bottom of the end assembly 1 has two waist-shaped holes, through which a pair of guide wheel assemblies 8 pass. Their axial movement is restricted by their own nuts and end caps. When the guide wheels need to be adjusted to hold the track, adjusting screws I9 pass through the side holes of the end assembly 1, press against the guide wheel assemblies 8, and are secured with adjusting nuts I10, thereby ensuring that the pair of guide wheels hold the track.

[0025] like Figure 3 、 Figure 4As shown. The running wheel box consists of a wheel box housing 13, end caps I 14, axle 15, sleeves I 16, running wheels 17, bearings 18, and sleeves I 19, and can be pre-assembled in the factory. The wheel box housing 13 serves as the main frame of the wheel box, with bearings 18 mounted on both sides. The axle 15 passes through the bearings 18 and running wheels 17 and is secured by end caps I 14, sleeves I 16, and sleeves I 19. To install the wheel box into the end assembly 1, first place it from the bottom of the end assembly 1, aligning the pin holes in the wheel box housing 13 with those in the end assembly 1. Then, install the pin 21 and end caps II 20, and tighten with screws 22, spring washers 23, and flat washers 24 to restrict radial movement of the wheel box. Then, use the multiple adjustment screws II 11 and adjustment nuts II 12 on both sides of the end assembly 1 to support the wheel box from both sides until the relative position of the running wheel 17 and the track meets the usage requirements. Then tighten the nuts to fix the axial position of the wheel box. After the wheel box is installed, the running motor 4 can be installed on the wheel axle 15 and then installed on the anti-torsion bracket 3.

[0026] The above-described embodiments merely represent specific implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the technical concept of the present application, and all such variations and improvements fall within the scope of protection of the present application.
