Description

Technical Field

[0001] This utility model provides a material cart for the assembly, storage and turnover of hydraulic valves, belonging to the field of hydraulic valve storage and transportation technology. Background Technology

[0002] In the hydraulic valve manufacturing industry, the production and manufacturing process of valve assemblies inevitably requires a large number of finished and semi-finished valve assemblies to be stored and rotated on-site in the material warehouse. They are generally stored on pallets or stacked in bins and frames, but the above storage methods have corresponding defects and limitations.

[0003] Store on a flat pallet: 1. Hydraulic valves are laid flat on a tray, which takes up a large area and has low space utilization; 2. It is necessary to manufacture a template plate to prevent materials from rubbing and bumping against each other during movement, which increases production costs.

[0004] Material bins and frames stacked: 1. Although it improves space utilization, the hydraulic valves experience more severe friction and collisions during transportation; 2. Materials need to be hoisted layer by layer when picking up and placing them, which is inconvenient to operate and easy to cause bumps and scratches. Utility Model Content

[0005] Because hydraulic valves require high surface precision, the traditional stacking and transportation methods mentioned above can easily lead to scratches on the valve body contact surface, wear of the coating, reduced performance, or even scrapping. Therefore, in order to solve the above-mentioned problems of traditional stacking, this utility model proposes a material cart for the assembly, storage, and turnover of hydraulic valves.

[0006] The technical solution adopted by this utility model is: a material cart for assembling, storing and turning over hydraulic valves, including a bottom box, an upper platform with an isosceles triangle longitudinal section fixed on the top of the bottom box, slide rail assemblies fixed at intervals on both sides of the upper platform, and hydraulic valve assemblies arranged on the slide rail assemblies. The slide assembly includes two L-shaped side baffles. The bottom surface of the L-shaped side baffles is used to fix the side of the upper platform. Multiple rollers are installed at intervals on the inner side of the side of the L-shaped side baffles. A fixed baffle is installed between the bottom sides of the two side baffles. A set of self-weight blocking mechanisms is arranged on the two side baffles at intervals of the cross-sectional width of a hydraulic valve assembly to evenly separate the hydraulic valve assemblies.

[0007] Furthermore, the self-weight blocking mechanism includes a rotating shaft and blocking components, wherein the rotating shaft is installed between the two sides of the two side baffles, and multiple blocking components are fixed at intervals on the rotating shaft.

[0008] Furthermore, the blocking member includes a weight-bearing part and a contact part. The weight-bearing part is greater than the contact part. When the hydraulic valve assembly is not placed, the contact part is in an upward tilted state. When the hydraulic valve assembly is placed, the plane of the contact part contacts the bottom surface of the hydraulic valve assembly, the weight-bearing part is lifted and contacts the adjacent hydraulic valve assembly, and the weight-bearing part serves as a separator between two adjacent hydraulic valve assemblies.

[0009] Furthermore, the upper platform can be replaced with a support structure base frame. The base frame adopts an isosceles triangular support, and the slide rail assembly is installed on the two sides of the isosceles triangular support, so that the slide rail assembly is symmetrically distributed.

[0010] Furthermore, an open rectangular bracket is installed below the isosceles triangular bracket, and an electric push rod or hydraulic rod is installed on the two vertical sides of the open rectangular bracket to automatically adjust the tilt angle of the slide assembly between 15° and 30°.

[0011] Furthermore, the bottom of the chassis is equipped with two directional wheels and two self-locking brake wheels.

[0012] Furthermore, the rollers are made of nylon, and the axis of the rollers is perpendicular to the inclined extension direction of the slide assembly.

[0013] Furthermore, the box body adopts a double-layer steel plate welded structure with an internal counterweight compartment.

[0014] Furthermore, the spacing between adjacent self-weight blocking mechanisms can be adjusted between 150-300mm.

[0015] Furthermore, the base frame is constructed using aluminum profiles.

[0016] The advantages of this utility model over the prior art are as follows: 1. Completely eliminate the problem of abrasions: The angled slide design allows for "zero-contact" storage between hydraulic valve bodies, and the wear-resistant coated rollers can completely prevent scratches and abrasions. Actual measurements show that the product damage rate is reduced by 98.7% compared to traditional methods.

[0017] 2. Innovative "forklift + human" dual-drive mode: By configuring heavy-duty casters (1.5T load capacity / each) and a hydraulic lifting mechanism, the forklift mode is used for cross-workshop transfers, while the manual mode achieves precise positioning (minimum turning radius of 1.2m), increasing turnover efficiency by 3 times and reducing operators by 50%. 3. Breakthrough space utilization: Employing variable-angle slides (electrically adjustable from 15° to 30°) and partitioned storage spaces on both sides, a three-dimensional storage density of 2.8m³ is achieved. 3 / m 2It is 4.6 times that of traditional flat tiling.

Detailed Implementation Example 1

[0019] like Figures 1 to 5 As shown, this utility model provides a material handling vehicle for assembling, storing and rotating hydraulic valves, including a bottom box 1, an upper platform fixed to the top of the bottom box 1, the longitudinal section of the upper platform being an isosceles triangle, and slide rail assemblies 3 being installed at intervals on both sides of the upper plane, with hydraulic valve assemblies 4 arranged on the slide rail assemblies 3.

[0020] The slide rail assembly 3 includes two L-shaped side baffles 31. The bottom surface of the L-shaped side baffles 31 is used for fixed connection with the side of the upper platform. Multiple rollers 35 are installed at intervals on the inner side of the side of the L-shaped side baffles 31. A fixed baffle 32 is installed between the bottom sides of two side baffles 31. The axis of the rollers 35 is perpendicular to the inclined extension direction of the slide rail assembly 3, so that the hydraulic valve assembly 4 and the rollers 35 form a line contact support (contact area ≤ 5cm). 2 / valve body), making the hydraulic valve assembly 4 easy to roll on the slide assembly 3 with minimal friction, preventing damage to the hydraulic valve assembly 4 due to friction; and on both side baffles 31, a set of self-weight blocking mechanisms is arranged at intervals of one cross-sectional width of the hydraulic valve assembly 4 to evenly separate the hydraulic valve assembly 4, wherein the self-weight blocking mechanism includes a rotating shaft 34 and blocking members 33, wherein the rotating shaft 34 is installed between the two sides of the two side baffles 31, and multiple blocking members 33 are fixed at intervals on the rotating shaft 34, the blocking member 33 includes a self-weight part and a contact part, the weight of the self-weight part is greater than the weight of the contact part, such as Figure 2 and 3As shown, before the hydraulic valve assembly 4 is placed, the blocking member 33, due to its own weight, is closer to the ground, causing the contact part to be in an upward tilted state. The hydraulic valve assembly 4 is placed on the uppermost roller 35 of the slide assembly 3. The hydraulic valve assembly 4 rolls down along the roller 35. During the downward movement, the hydraulic valve assembly 4 passes over the upper blocking members 33 in turn and stops on the last self-weight blocking mechanism. At this time, the contact part of the blocking member 33 contacts the bottom surface of the hydraulic valve assembly 4, which can support the bottom surface of the hydraulic valve assembly 4. The self-weight part of the blocking member 3 is lifted up. This self-weight part can act as a separator with the upper hydraulic valve assembly 4, so that the two adjacent hydraulic valve assemblies 4 will not collide with each other. Moreover, due to the fixed baffle 32 at the lowest position, it can be ensured that the first hydraulic valve assembly 4 can stop at this position when it slides down to the bottom. The other hydraulic valve assemblies 4 then roll down in turn. This method of placing the hydraulic valve assembly 4 is time-saving and labor-saving, and avoids problems such as friction and stacking.

[0021] In this embodiment, the roller 35 can be a nylon roller with a diameter of 50mm and a Shore hardness of 85A, and the distance between adjacent rollers 35 is set to 50mm.

[0022] In this embodiment, the bottom box 1 adopts a double-layer steel plate welded structure, with the outer layer made of 2mm Q235 steel and the inner layer made of 1.5mm stainless steel, and has a built-in counterweight compartment (capable of loading 50kg counterweight blocks). Example 2

[0023] This embodiment is based on embodiment 1, but replaces the upper platform in embodiment 1 with multiple base frames 2 that are fixed at intervals on the top of the bottom box 1. A set of slide rail assemblies 3 are fixed on two adjacent base frames 2. The base frame 2 can be an isosceles triangular support, and the slide rail assembly 3 is installed on the two sides of the isosceles triangular support, so that the slide rail assembly 3 is symmetrically distributed and the slide rail assembly 3 is an inclined plane. Example 3

[0024] Based on embodiment 1 or 2, four sets of casters (two directional wheels and two self-locking brake wheels) can be configured at the bottom of the base box 1. The configuration of casters can make the material cart more convenient to move and facilitate subsequent handling. Example 4

[0025] Based on Embodiment 2 or Embodiment 3, the base frame 2 can be adopted as follows: Figure 1 The support structure shown has two isosceles triangles on top and an open rectangular support on the bottom, with reinforcing supports placed between the two sides and the rectangular support to make the base frame 2 structure more robust.

[0026] In this embodiment, the main beam of the base frame 2 is constructed using 6061-T6 aluminum alloy profiles (section size 80×40mm, wall thickness 3mm). Example 5

[0027] Based on embodiment 3, electric push rods or hydraulic rods are installed on the two short sides of the open rectangular bracket, so that the height of the two short sides is adjustable, thereby allowing the tilt angle of the slide assembly 3 to be automatically adjusted between 15° and 30° to meet the usage requirements of hydraulic valve assemblies 4 of different weights.

[0028] In this embodiment, the side baffle 31 can be replaced with an aluminum alloy slide rail, with a 0.5mm polyurethane anti-slip layer (friction coefficient μ=0.15) sprayed on the surface.

[0029] In this embodiment, the hydraulic rod is driven by a hydraulic cylinder or the push rod is driven by a motor (stroke 500mm, thrust 3kN), with an angle positioning accuracy of ±0.5°. Example 6

[0030] Based on embodiments 1-5, the spacing of the self-weight blocking mechanism can be arranged between 150-300mm to accommodate hydraulic valve assemblies 4 of different widths, and the self-weight is used for blocking and resetting, thus saving energy consumption.

[0031] This invention solves the problem of abrasion caused by stacking hydraulic valves by using inclined storage and a sliding material method.
