Description

Technical Field

[0001] The utility model relates to the technical field of busbar carbon brush holders, and more particularly to a busbar carbon brush holder for a gantry crane. Background Art

[0002] Gantry cranes, also known as portal cranes or bridge cranes, are primarily used for handling heavy loads and are commonly found in places like ports, freight yards, shipyards, construction sites, and large manufacturing plants. The gantry crane busbar system is a device specifically designed to provide power to the gantry crane. This system enables the gantry crane to continuously receive power as it moves on the track, thereby driving its movement and operating loads. The busbar carbon brush holder, also known as the collector holder, is a key component in the busbar system used to support and guide the carbon brushes. In the busbar system, the function of the carbon brushes is to establish stable electrical contact between the collector and the busbar rail to transmit power to the moving equipment.

[0003] The carbon brush holders of the gantry crane's busbar are composed of two groups, front and back, which are connected together. However, when a carbon brush holder in one group breaks or fails, inertia will cause a chain reaction failure in the other group, which not only increases the damage to the busbar but also increases the risk and maintenance costs. Moreover, when the two connected groups of carbon brush holders are deformed, worn or fail, it is very difficult to repair and replace them, which is time-consuming and labor-intensive, and has low operating efficiency.

[0004] Therefore, it is necessary to provide a gantry crane busbar carbon brush holder to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a gantry crane busbar carbon brush holder to solve the above technical problems.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A gantry crane busbar carbon brush holder is provided on a busbar guide rail and includes a collector frame and further includes:

[0008] A fixed steel plate is provided on the gantry crane, and a mounting plate is provided on the fixed steel plate;

[0009] Two mounting posts are provided on the mounting plate;

[0010] a connecting piece connected to the collector frame, wherein the connecting piece is provided with a first clamping groove adapted to the mounting column, and first fixing holes are provided on both sides of the first clamping groove;

[0011] A fixing member is detachably connected to the connecting member, and the fixing member is provided with a second clamping groove adapted to the mounting column, and second fixing holes adapted to the first fixing holes are opened on both sides of the second clamping groove.

[0012] Furthermore, the mounting post is provided with a plurality of limiting mechanisms for limiting the movement of the connecting member and the fixing member.

[0013] Furthermore, the limiting mechanism includes:

[0014] Two limiting plates are provided on the mounting post, a baffle is movably sleeved on the mounting post, and the connecting member and the fixing member are located between the two limiting plates;

[0015] An adjusting component is provided on the limiting plate and is used for adjusting the position of the baffle on the mounting column.

[0016] Furthermore, the adjusting component includes:

[0017] A connecting block is provided on the limiting plate, and a screw is rotatably provided on the connecting block;

[0018] The adjusting block is arranged on the baffle, and the adjusting block is threadedly connected to the screw.

[0019] Furthermore, a rotating block and a stopper are respectively provided at both ends of the screw, and a socket is provided on the rotating block.

[0020] Furthermore, auxiliary holes are provided on the baffles, and the auxiliary holes on two baffles are connected by bolts.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this solution, the two sets of carbon brush holders are separated from each other, that is, the collector racks are separate. If the carbon brush holder on one set of mounting posts breaks or the connecting rod is damaged, the carbon brush holder on the other set of mounting posts will not be affected, thus avoiding cascading failures. This greatly reduces the damage to the busbar, reduces the risk, and reduces labor intensity and maintenance costs. Furthermore, there is a large space between the two sets of collector racks. If the two sets of carbon brush holders become deformed, worn, or malfunction, the difficulty of repairing them, which is currently caused by connecting them together, is greatly avoided. Repair or replacement is simpler and more convenient, saving a lot of time and labor, significantly improving work efficiency, and can be widely promoted and used.

[0023] 2. In this solution, the fixing parts and the connecting parts are further restricted by the limiting mechanism. When the fixing parts and the connecting parts are unstable on the mounting column, they can be blocked by the limiting mechanism, which greatly prevents the fixing parts and the connecting parts from being offset on the mounting column, that is, it prevents the collector rack from being offset during use, effectively ensures the normal use of the collector rack, and is highly practical.

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0034] In addition, if the embodiments of the present invention include descriptions of "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0035] Example 1:

[0036] See also Figure 1-4 A gantry crane busbar carbon brush holder is provided on a busbar guide rail 1 and includes a collector frame 2, and also includes: a fixed steel plate 3, provided on the gantry crane, and a mounting plate 4 is provided on the fixed steel plate 3; two mounting columns 5 are provided on the mounting plate 4; a connecting piece 6, connected to the collector frame 2, and a first clamping groove 7 is provided on the connecting piece 6 to match the mounting column 5, and first fixing holes 8 are provided on both sides of the first clamping groove 7; a fixing piece 9, detachably connected to the connecting piece 6, and a second clamping groove 10 is provided on the fixing piece 9 to match the mounting column 5, and second fixing holes 11 are provided on both sides of the second clamping groove 10 to match the first fixing hole 8.

[0037] The two groups of carbon brush holders in the present application are separated. When installing each group of collector racks 2, first place the connector 6 of the collector rack 2 on the mounting post 5 at the corresponding position of the mounting plate 4, so that the first clamping groove 7 of the connector 6 is clamped on the mounting post 5, and then place the fixing member 9 on the mounting post 5 at the position where the connector 6 is located, so that the second clamping groove 10 clamps the mounting post 5, and makes the second fixing hole 11 of the fixing member 9 and the first fixing hole 8 of the connector 6 correspond to each other, and then pass the bolt through the first fixing hole 8 and the second fixing hole 11, and then fix them with the nut and bolt, so that the fixing member 9 and the connector 6 can be fixed on the mounting post 5, and at this time, one end of the collector rack 2 is connected to the mounting post 5. In this method, the two sets of carbon brush holders are separated from each other, that is, the collector racks 2 are separated. If the carbon brush holders on the mounting posts 5 of one set fail, such as breaking or the connecting rod being damaged, the carbon brush holders on the other set of mounting posts 5 remain unaffected, thus avoiding cascading failures. This significantly reduces damage to the busbar, reduces risk, and reduces labor intensity and maintenance costs. Furthermore, the space between the two sets of collector racks 2 is also large. If the two sets of carbon brush holders become deformed, worn, or fail, the difficulty of repairing them, which is currently caused by being connected together, is greatly avoided. Repair or replacement is much simpler and more convenient, saving a lot of time and labor, significantly improving work efficiency, and can be widely adopted.

[0038] Example 2:

[0039] See also Figure 1-6 Based on the first embodiment, the mounting post 5 is provided with a plurality of limiting mechanisms 12 for limiting the movement of the connector 6 and the fixing member 9. When the fixing member 9 and the connector 6 are fixed to the mounting post 5, both the fixing member 9 and the connector 6 are located in the position of the limiting mechanism 12. After the fixing member 9 and the connector 6 are fixed, the limiting mechanism 12 further limits the fixing member 9 and the connector 6. When the fixing member 9 and the connector 6 are unstable on the mounting post 5, they can be blocked by the limiting mechanism 12. This greatly prevents the fixing member 9 and the connector 6 from shifting on the mounting post 5. In other words, it prevents the collector rack 2 from shifting during use, effectively ensuring the normal use of the collector rack 2 and having strong practicality.

[0040] In this embodiment, preferably, please refer to Figure 5-6The limiting mechanism 12 includes two limiting plates 121 mounted on the mounting post 5. A baffle 122 is movably mounted on the mounting post 5, with the connector 6 and the fixing member 9 positioned between the two limiting plates 121. An adjusting component 123 is mounted on the limiting plates 121 and is used to adjust the position of the baffle 122 on the mounting post 5. After the fixing member 9 and the connector 6 are secured to the mounting post 5, the adjusting component 123 drives the baffle 122 to move, thereby adjusting the position of the baffle 122 so that the baffle 122 abuts against the connector 6 and the fixing member 9, thereby limiting their movement. Furthermore, the two limiting plates 121 effectively pre-position the fixing member 9 and the connector 6, allowing staff to more clearly understand the installation positions of the fixing member 9 and the connector 6.

[0041] In this embodiment, preferably, please refer to Figure 5-6 The adjustment component 123 includes a connecting block 1231 mounted on the limiting plate 121 and rotatably provided with a screw 1232; and an adjustment block 1233 mounted on the baffle 122 and threadedly connected to the screw 1232. Rotating the screw 1232 drives the adjustment block 1233 to move horizontally, which in turn causes the baffle 122 to move along the mounting post 5, ultimately causing the baffle 122 to abut against the connector 6 and the fixing member 9.

[0042] In this embodiment, preferably, please refer to Figure 6 The screw rod 1232 is provided with a rotating block 13 and a stopper 14 at both ends thereof, and a socket 15 is provided on the rotating block 13. The screw rod 1232 can be rotated by rotating the rotating block 13, and the screw rod 1232 can be rotated more conveniently by inserting a rod-shaped object such as a pin into the socket 15 of the rotating block 13.

[0043] In this embodiment, preferably, please refer to Figure 6 The baffles 122 are provided with auxiliary holes 16, and the auxiliary holes 16 on the two baffles 122 are connected by bolts. After the baffles 122 are finally against the connecting piece 6 and the fixing piece 9, the bolts are inserted into the auxiliary holes 16 on the two baffles 122 and then tightened with nuts to further improve the blocking effect of the baffles 122 on the connecting piece 6 and the fixing piece 9.

[0044] It should be understood that the examples and implementation methods described herein are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art may make various modifications or changes based on them. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0045] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indications will also change accordingly.

[0046] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.
