Description

Technical Field

[0001] This application relates to the field of mechanical equipment technology, and specifically proposes a display screen assembly and a tire crane. Background Technology

[0002] A rubber-tired gantry crane, also known as a mobile gantry crane, is a large container handling equipment mainly used for loading, unloading, and stacking operations at port terminals and container yards. Its core feature is its reliance on a tire-based walking system for movement. With technological advancements, rubber-tired gantry cranes are now commonly equipped with guidance displays, allowing container truck drivers to determine parking locations by observing the information on the displays, thus enabling them to complete operations smoothly.

[0003] However, traditional tire cranes typically have the display screen fixed to two support columns. Truck drivers can only observe it normally before they are directly under the tire crane. As the truck moves, the driver's field of view gradually narrows. When the truck is near the area directly under the tire crane, the field of view becomes limited. Furthermore, when the truck leaves the area directly under the tire crane, it is impossible to obtain the information on the display screen through the rearview mirror. Utility Model Content

[0022] The embodiments of this application are described below with reference to the accompanying drawings. It can be understood that the technical features involved in the different embodiments described below can be combined with each other as long as they do not conflict with each other.

[0023] Firstly, referring to Figures 1 to 4 This application discloses a display assembly, which includes a support assembly and a display unit 40. The support assembly includes a bracket 10, a rotating part 20, and a locking structure 30. The rotating part 20 is rotatably connected to the bracket 10. The display unit 40 is connected to the rotating part 20 and is rotatably adjustable relative to the bracket 10 through the rotating part 20. The locking structure 30 can lock the relative rotation between the display unit 40 and the rotating part 20.

[0024] In this embodiment, by adjusting the angle of the rotating part 20 and the height of the bracket 10, the multi-directional observation angle adjustment of the display unit 40 is realized, ensuring that the truck driver can clearly observe the screen content from in front of, directly below, or through the rearview mirror of the tire crane. The structure of this application is stable and reliable, and the adjustment is convenient, which significantly improves the work efficiency and safety.

[0025] Specifically, the bracket 10 adopts a modular design, which is convenient for installation and maintenance; the rotating part 20 achieves precise positioning through the locking structure 30, which avoids positional deviation during operation; the display unit 40 adopts a high-brightness display module to ensure that guidance information can be clearly displayed under various lighting conditions.

[0026] Optionally, the display screen assembly in this embodiment is suitable for guidance systems of various port machinery and equipment, such as tire cranes.

[0027] In some embodiments, refer to Figures 1 to 3 The bracket 10 includes a first component 110 and a second component 120. The first component 110 has a mounting portion 114 arranged in a vertical direction, and the second component 120 is adjustablely connected to the mounting portion 114 in a vertical direction. The rotating portion 20 is rotatably connected to the second component 120.

[0028] In this embodiment, the first component 110 is a fixed base component, and the second component 120 is a movable adjustment component. The second component 120 is vertically adjusted relative to the first component 110 along the mounting part 114, thereby realizing the vertical adjustment of the display screen unit 40, which is convenient for the driver to observe; the rotating part 20 achieves the rotation effect by connecting with the second component 120.

[0029] In some embodiments, refer to Figure 1 and Figure 2 The mounting part 114 has multiple adjustment points, which are spaced apart along the vertical direction, and the second component 120 can be connected to any one of the adjustment points.

[0030] Optionally, the mounting part 114 in this embodiment can adopt a slide rail structure or an anchor point connection structure, both of which can realize the vertical movement adjustment of the second component 120 relative to the first component 110.

[0031] Specifically, the second component 120 can be connected to the adjustment point by bolts, and the height can be quickly adjusted by loosening the bolts to ensure that the display unit 40 is always at the optimal viewing height.

[0032] In some embodiments, the optimal observation height is 2.5m-3.1m, the spacing between adjustment points is 90±5mm, and the total length of the mounting part 114, that is, the maximum adjustable range of the second component 120 in the vertical direction, is 900mm.

[0033] In some embodiments, refer to Figures 1 to 3 The second component 120 includes a mating part 121 and a rotating shaft 122. The rotating shaft 122 is disposed on the mating part 121, and the mating part 121 is provided with a first arc-shaped hole 123. The rotating part 20 includes a turntable 210, which corresponds to the mating part 121. The turntable 210 can rotate around the rotating shaft 122. The turntable 210 is provided with a second arc-shaped hole. The locking structure 30 can pass through the first arc-shaped hole 123 and the second arc-shaped part and lock the turntable 210 and the mating part 121.

[0034] In this embodiment, a method is proposed to enable the second component 120 to rotate relative to the first component 110. Specifically, the second component 120 and the turntable 210 achieve stepless angle adjustment by using the cooperation of the first arc-shaped hole 123 and the second arc-shaped hole, and are locked by the locking structure 30 to ensure a large adjustment angle range and a reliable fixed position after adjustment.

[0035] Optionally, the adjustable range of the rotation angle of the rotating part 20 in this embodiment is 0-360°, and in some embodiments, 0-70° is the optimal range, which enables the driver to obtain a good field of vision to complete the operation.

[0036] Optionally, the locking structure 30 may, but is not limited to, use anti-loosening bolts.

[0037] In some embodiments, refer to Figures 1 to 3 The rotating part 20 also includes a first support member 220 and a second support member 230. The first support member 220 and the second support member 230 are arranged at an angle and are connected between the display unit 40 and the turntable 210. The display unit 40 rotates synchronously with the turntable 210 through the first support member 220 and the second support member 230.

[0038] In this embodiment, a stable triangular support structure is formed between the bottom of the turntable 210, the first support member 220, and the second support member 230, which effectively disperses the gravity of the display unit 40 and the external forces under the usage scenario, improves the stability of the overall structure, and ensures that the display unit does not fall off.

[0039] In some embodiments, refer to Figure 1 The first component 110 includes a first rod 111, a second rod 112 and a third rod 113. The first rod 111 and the second rod 112 are spaced apart. The third rod 113 is connected between the first rod 111 and the second rod 112, and the third rod 113 has a mounting part 114.

[0040] In this embodiment, the rods of the first component 110 are connected by welding, such as... Figure 1 As shown, it forms a "C" shaped structure, with high overall structural strength and stability.

[0041] Secondly, this application proposes a tire-mounted crane, including the display assembly of the first aspect.

[0042] In this embodiment, the tire crane of the second aspect includes the display screen assembly of the first aspect, and therefore the tire crane of the second aspect includes all the technical effects of the display screen assembly of the first aspect.

[0043] In some embodiments, the tire crane includes two spaced-apart support columns 50, and each support column 50 has two spaced-apart tire mechanisms 60 (the tire mechanism 60 includes, but is not limited to, tires, suspensions, bearing components, etc.) at its bottom. A beam 70 is provided between the two sets of tire mechanisms 60, and the display screen assembly is mounted on the beam 70.

[0044] Optionally, the display screen assembly can be installed at any suitable location on the tire crane to meet the driver's observation needs, including but not limited to the beam 70, support column 50, etc., wherein in some embodiments, the beam is the optimal installation location.

[0045] It should be noted that, in addition to the display screen assembly, the tire crane may also include a hydraulic pump, engine, etc. Other components will not be described in detail.

[0046] In some embodiments, the bracket 10 includes an embedded part 115 and a limiting part 116. The embedded part 115 is inserted into the beam 70, and the limiting part 116 abuts against the beam 70 and limits the insertion depth of the embedded part 115.

[0047] In this embodiment, the limiting part 116 ensures accurate installation position and prevents the pre-embedded part 115 from being over-inserted. The dimensions of the pre-embedded part 115 and the limiting part 116 can be changed according to the actual size of the tire crane.

[0048] Optionally, the embedded part 115 may, but is not limited to, use a 200mm long anchor bolt, and the limiting part 116 may, but is not limited to, use a 15mm thick steel plate.

[0049] In some embodiments, the bracket 10 can be adjusted in the direction away from or close to the beam 70 by means of a telescopic mechanism or by changing the length of the rod.

[0050] In this embodiment, the bracket 10 can be adjusted horizontally by changing the length of the rod, which is convenient to adapt to the installation requirements of different models of tire cranes, and also facilitates daily maintenance and replacement.

[0051] The embodiments of this application also include a method for installing and debugging the display screen assembly: first, the embedded part 115 is fixed to the predetermined position of the beam 70, then the first component 110 and the second component 120 are installed, and after being adjusted to the required length, the connecting bolts are tightened; then the rotating part 20 and the display screen unit 40 are installed, and after being adjusted to the optimal viewing angle, the locking structure 30 is locked; finally, a functional test is performed to ensure that each adjustment mechanism works normally.

[0052] In particular, the term "and / or" in this application should be understood as follows: In the first case, the term “and / or” between the first subject and the second subject includes any of the following meanings: (1) only the first subject; (2) only the second subject; and (3) both the first subject and the second subject.

[0053] In the second case, the term "and / or" between the last two of three or more subjects means including at least one of the subjects. For example, "first subject, second subject and / or third subject" has the same meaning as "first subject and / or second subject and / or third subject", specifically including the following combinations: (1) only the first subject; (2) only the second subject; (3) only the third subject; (4) first subject and second subject and no third subject; (5) first subject and third subject and no second subject; (6) second subject and third subject and no first subject; and (7) first subject, second subject and third subject; Furthermore, the character " / " in this application indicates that the objects before and after it are in an "or" relationship.
