Description

Technical Field

[0001] The utility model belongs to the technical field of port machinery lighting, and in particular relates to a lamp holder used on the side of a driver's cab of a port machinery equipment. Background Art

[0002] The basic height of port machinery equipment is tens of meters. In order to ensure a good view for the driver, the height of the driver's cab is basically more than ten meters above the ground. At the same time, in order to prevent the driver's line of sight from being blocked, the platform for entering and exiting the driver's cab is only set on one side of the driver's cab. In order to ensure the illumination at night, it is necessary to set a lighting lamp on the side of the driver's cab without a platform. The present invention mainly solves the seismic resistance and maintenance convenience of the lighting fixture on the side of the driver's cab without a platform.

[0003] In port machinery equipment, especially port machinery equipment such as yard cranes, quay cranes, and bridge grabs, the driver's cab needs to move with the trolley. Since the trolley moves fast and there is a hard connection between the driver's cab and the trolley, the vibration frequency of the driver's cab shell is relatively large. If the lighting fixture on the driver's cab shell is not fixed properly, it will be damaged due to vibration fatigue. In order to ensure the driver's field of vision, no maintenance platform is set near the lighting fixture, so the maintenance of this lighting fixture is very inconvenient.

[0004] A relatively simple method in the prior art is to directly weld the lamp holder to the outer wall of the driver's room. This direct welding method can neither avoid vibration nor be convenient for maintenance.

[0005] Another way to light the rack is as follows Figure 1 As shown, in order to install the lamp on a lamp pole 12 more than 2 meters long, the lamp holder 13 bracket is welded to the outside of the driver's cab, and each lamp pole 12 is fixed with two lamp holders 13. Each lamp holder 13 is composed of four parts: a lamp holder 13 fixing bracket, a guide plate, a support plate and a spring. The specific structure of the lamp pole 12 and the lamp holder 13 can refer to the Chinese utility model patent with publication number CN210319708U. When the lamp fails, the maintenance personnel can grab the lamp pole 12 inside the driver's cab and pull it upward, and lift the lamp pole 12 together with the lighting lamp into the driver's cab, which brings convenience to maintenance and improves maintenance efficiency. At the same time, maintenance in the driver's cab can also ensure safety.

[0006] However, due to the high-frequency vibration during the movement of the cab, Figure 1 The spring of the center lamp frame cannot press the guide plate all the time, so the lighting lamp shakes particularly severely. The shaking causes the lamp to be easily damaged and the shaking of the light is particularly easy to cause visual fatigue to the driver; and Figure 1 The lamp stand is not convenient for adjusting the lighting angle. Summary of the invention

[0007] The purpose of the utility model is to solve the problems mentioned in the background technology and to provide a lamp stand for the side of the driver's cab of port machinery equipment, which can reduce the shaking of the lamp stand caused by vibration during the movement of the driver's cab, thereby increasing the life of the lamp stand and reducing the visual fatigue of the driver caused by the shaking of the lamp stand, and also facilitates the adjustment of the lighting angle.

[0008] In order to achieve the above technical purpose, the technical solution adopted by the utility model is:

[0009] A lamp stand for the side of a driver's cab of a port machinery equipment comprises a plurality of lower ear plates and matching upper ear plates, wherein the lower ear plates and the upper ear plates are correspondingly arranged on the side of the driver's cab, a lamp connector is hinged on the lower ear plate, a telescopic pull rod is connected between the lamp connector and the upper ear plate, and the telescopic pull rod is hinged to the lamp connector.

[0010] Preferably, the telescopic pull rod is hinged to the upper ear plate.

[0011] Preferably, copper sleeves are provided in the hinge holes between the lamp connector and the lower ear plate and the telescopic pull rod, and in the hinge holes between the telescopic pull rod and the upper ear plate.

[0012] Preferably, the telescopic pull rod comprises a long screw and a short screw, wherein a threaded sleeve is connected between the long screw and the short screw; the outer ends of the long screw and the short screw are both provided with a U-shaped frame, and the U-shaped frame is hinged on the upper ear plate or the lamp connector.

[0013] Preferably, the lamp connector is provided with a hinged plate matching the telescopic pull rod.

[0014] Preferably, a safety rope is connected between the lamp connector and the side of the driver's cab.

[0015] Preferably, the lamp connector is provided with a plurality of waist-shaped holes.

[0016] Preferably, the lamp connecting member is a U-shaped frame, the inner ends of the two side rods of the U-shaped frame are hinged on the lower ear plate, and the telescopic pull rod is connected to the outer ends of the two side rods of the U-shaped frame.

[0017] Preferably, a plurality of reinforcing rods are connected between the two side rods of the U-shaped frame.

[0018] The beneficial effects of the utility model are:

[0019] The lamp connector of the present application is connected to the side of the driver's cab by a telescopic pull rod to form a triangular stable structure. Compared with the prior art, it can be more firmly connected to the driver's cab and reduce the overall shaking of the lamp stand. On the one hand, it avoids damage to the lamp stand due to frequent shaking. On the other hand, the reduced shaking of the lamp stand also avoids the shaking of the light during the lighting process, reducing the driver's visual fatigue.

[0020] The telescopic rod of the present application can adjust its overall length through a threaded sleeve, and by adjusting the length of the telescopic rod, the inclination angle of the lamp connector can be adjusted, thereby adjusting the lighting angle. Compared with the fixed lighting angle in the prior art, the lamp stand provided by the present application is more practical and convenient.

[0021] The present application connects the lamp connector to the side of the driver's cab by means of a telescopic pull rod and upper and lower ear plates. When maintenance is needed, the telescopic pull rod is simply removed from the upper ear plate, and then the telescopic pull rod is pulled to rotate and lift the lamp connector to the driver's cab window for maintenance. A safety rope is also provided on the lamp connector, and the lamp connector can be fixed by the safety rope during the maintenance process. After the maintenance is completed, the safety rope is first untied, the lamp connector is rotated and placed at a suitable height, and then the safety rope is fixed and the telescopic pull rod and the upper ear plate are connected. Compared with the prior art, the entire lamp pole and lighting equipment are directly lifted and put into the driver's cab for maintenance. After the repair, the lamp pole and lighting equipment must be lifted and plugged into the lamp holder. The whole process of directly lifting the lamp pole and lighting equipment is relatively laborious. The present application saves more effort by rotating and lifting the lamp connector, making maintenance more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings.

[0034] It should be noted that the terms such as "upper", "lower", "left", "right", "front", "back", etc. used in the utility model are only for the convenience of description and are not used to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of implementation of the present utility model without substantially changing the technical content.

[0035] like Figure 1-9 As shown, the present application provides a lamp stand for the side of the driver's cab of a port machinery equipment, including two lower ear plates 1 and a matching upper ear plate 2, and the number of the two ear plates can be set according to actual conditions.

[0036] The lower ear plate 1 and the upper ear plate 2 are correspondingly arranged on the side of the driver's cab. A lamp connector 3 is hinged on the lower ear plate 1. A telescopic pull rod 4 is connected between the lamp connector 3 and the upper ear plate 2. The telescopic pull rod 4 is hinged to the lamp connector 3.

[0037] The telescopic pull rod 4 and the upper ear plate 2 can also be hinged by a pin, or of course bolted. Whether the telescopic pull rod 4 and the upper ear plate 2 can rotate relative to each other after being connected does not affect the overall function of the lamp stand.

[0038] Copper sleeves 10 are provided in the hinge holes of the lamp connector 3 and the lower ear plate 1 and the telescopic rod 4, as well as in the hinge holes of the telescopic rod 4 and the upper ear plate 2. The copper sleeves 10 are equivalent to bearings, which reduce the wear of the hinge shaft. A small gap can be used between the hinge shaft and the copper sleeve 10, that is, it is necessary to ensure the normal rotation of the hinge, and at the same time, a large gap should not appear between the hinge shaft and the copper sleeve 10, which increases the shaking gap between the various parts of the lamp stand and reduces the overall stability of the lamp stand.

[0039] The telescopic pull rod 4 includes a long screw 5 and a short screw 6, and a threaded sleeve 7 is connected between the long screw 5 and the short screw 6; the outer ends of the long screw 5 and the short screw 6 are provided with a U-shaped frame, and the U-shaped frame is hinged on the upper ear plate 2 or the lamp connector 3. Preferably, the U-shaped frame at the outer end of the short screw 6 is connected to the upper ear plate 2, and the U-shaped frame at the outer end of the long screw 5 is connected to the lamp connector 3, so that the threaded sleeve 7 will be closer to the driver's cab side, which is convenient for subsequent rotation of the threaded sleeve 7 to adjust the overall length of the telescopic pull rod 4, and then adjust the lighting angle; fastening nuts 12 can also be provided on the long screw 5 and the short screw 6 to limit the axial movement of the threaded sleeve 7.

[0040] The lamp connecting member 3 is a U-shaped frame, the inner ends of the two side rods of the U-shaped frame are hinged on the lower ear plate 1, and the telescopic pull rod 4 is connected to the outer ends of the two side rods of the U-shaped frame. Hinge holes can be directly set at the outer ends of the two side rods of the U-shaped frame, or hinge plates can be set at the outer ends of the two side rods of the U-shaped frame for hinge connection with the telescopic pull rod 4.

[0041] A safety rope 9 is connected between the lamp connector 3 and the side of the driver's cab. A connecting plate can be set on the bottom rod of the U-shaped frame (or the bottom plate, the two side rods and the bottom rod of the U-shaped frame can both be rod-shaped or plate-shaped), and a corresponding connecting plate is also set on the side of the driver's cab. Through holes matching the safety rope 9 can be provided on the two connecting plates, and the safety rope 9 is tied in the through holes of the connecting plates. Of course, the safety rope 9 can also be set in other ways, such as providing a screw on the bottom rod of the U-shaped frame and the side of the driver's cab, and the safety rope 9 can be tied thereto.

[0042] The lamp connector 3 is provided with a plurality of waist-shaped holes 11 , which can be arranged on the bottom rod of the U-shaped frame. The waist-shaped holes 11 are arranged to adapt to different types of lamp sizes and improve the applicability of the device.

[0043] A plurality of reinforcing rods are connected between the two side rods of the U-shaped frame. The reinforcement rods can improve the overall strength of the U-shaped frame and improve the stability of the device.

[0044] The working principle of a lamp stand for the side of the driver's cab of a port machinery equipment provided in this application is as follows:

[0045] When in use, link the inner end of the lamp connector 3 to the lower ear plate 1, bolt the lamp to the waist-shaped hole 11 of the lamp connector 3, connect the telescopic rod 4 and one end of the safety rope 9 to the lamp connector 3, gradually lengthen the safety rope 9 to rotate and lower the lamp connector 3 to a suitable position, and then link the safety rope 9 to the side of the driver's cab; then connect the upper end of the telescopic rod 4 to the upper ear plate 2.

[0046] If the lighting angle needs to be adjusted, the safety rope 9 can be loosened, and then the threaded sleeve 7 on the telescopic rod 4 can be rotated to adjust the length of the telescopic rod 4, thereby adjusting the inclination angle of the lamp connector 3 relative to the horizontal plane, and then adjusting the lighting angle of the lamp. After the adjustment, the safety rope 9 can be connected to the side of the driver's cab. In addition to pulling the lamp connector 3, the safety rope 9 can also play an additional role in normal times. Under normal circumstances, the safety rope 9 can be in a relaxed state to prevent it from fatigue fracture due to slight shaking of the lamp connector 3. After the lamp stand has been used for a long time, if the various connections of the lamp connector 3 are loosened due to slight vibrations, the safety rope 9 can also hold the lamp connector 3 to prevent it from falling.

[0047] If maintenance is required, loosen the safety rope 9, remove the connection between the telescopic rod 4 and the upper ear plate 2, and then rotate and stretch the lamp connector 3 to the driver's cab window through the safety rope 9 for maintenance. After repair, repeat the above installation process and rotate and lower the lamp connector 3 to a suitable position.

[0048] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the utility model.
