[0002] A gantry crane is an electromechanical equipment consisting of a traveling mechanism, a rotating mechanism, a lifting mechanism, a luffing mechanism, and a boom system. It is generally used for loading and unloading cargo in coastal and riverside areas. It is efficient, safe, and energy-saving, and is an important part of port operations and production. At present, in the existing technology, the sound and light alarm on the gantry crane is vertically installed on the outdoor gantry leg bracket. During the walking process, it will emit an alarm sound and a rotating flash light to remind people around to pay attention to safety. During this walking process, since the alarm speaker volume hole of the sound and light alarm placed vertically on the column is located on the side of the entire gantry crane, this position is easily soaked by rainwater when it rains, and the waterproof and sealing properties are relatively weak. In the face of heavy rain, it is often burned out due to water short circuit, the maintenance cost is high, the maintenance workload is large, and the utilization rate is low. Utility Model Content

[0003] The main purpose of the utility model is to provide a portal crane with a walking sound and light alarm, aiming to solve the technical problems that the sound and light alarm on the portal crane has weak waterproofness and sealing, often gets into water and short-circuits and is burned out, resulting in high maintenance costs, large maintenance workload and low utilization rate.

[0004] To achieve the above-mentioned purpose, the present invention provides a walking sound and light alarm, comprising:

[0032] The present invention proposes a portal crane 3 with a walking sound and light alarm. In the embodiment of the present invention, Figures 1 to 7 As shown, the portal crane 3 of the walking sound and light alarm 2 includes:

[0033] The traveling mechanism 31 is provided with columns 313, and the columns 313 include land side columns 313A and sea side columns 313B.

[0034] The lifting mechanism 33, the traveling mechanism 31 and the lifting mechanism 33 are connected via a rotating mechanism 32;

[0035] A luffing mechanism 34 is provided on the lifting mechanism 33 and is used to adjust the amplitude of the portal crane 3;

[0036] The sound and light alarm 2 includes a sea-side sound alarm 22 and a land-side sound and light alarm 21. The sea-side sound alarm 22 and the land-side sound and light alarm 21 are respectively provided with a sea-side horn volume hole 24 and a land-side horn volume hole 23, and are both arranged vertically downward;

[0037] The bracket 1 is installed on the column 313 . The bracket 1 includes a horizontal portion 11 and a vertical portion 12 forming a right angle with the horizontal portion 11 . The sound and light alarm 2 is fixedly installed on the vertical portion 12 .

[0038] Specifically, the horizontal portion 11 and the vertical portion 12 of the bracket 1 are of an integrated structure, and the horizontal portion 11 and the vertical portion 12 are vertically bent in the middle section. The integrated structure helps to save process costs.

[0039] Specifically, the thickness of the bracket 1 is 3 mm. The bracket 1 adopts a size of 20*20 cm and is bent 90 degrees in the middle to form the bracket 1 having a horizontal portion 11 and a vertical portion 12.

[0040] Specifically, the bracket 1 is installed in the middle position between the landside column 313A and the seaside column 313B.

[0041] Specifically, the bracket 1 is made of stainless steel plate and the surface is painted, and the paint coating has the functions of anti-corrosion and distinguishing components.

[0042] In this embodiment, at least one sound and light alarm 2 is provided on both sides of the operating mechanism. Since the gantry crane 3 itself is large in size, arranging the sound and light alarm 2 on both sides is beneficial to signal transmission, that is, the land side sound and light alarm 21 is provided on the land side, including the land side horn volume hole 23; the other side, that is, the sea side, is provided with a sea side sound and light alarm 22, including the sea side horn volume hole 24.

[0043] Specifically, the sound and light alarm 2 has a cylindrical appearance and is used for efficient transmission of light signals.

[0044] Specifically, the sound and light alarm 2 is fixedly mounted on the outer side of the vertical portion 12 through a threaded connection.

[0045] Specifically, the horn volume hole 23 of the sound and light alarm 2 is set through the surface of the bottom of the sound and light alarm 2, and the horn volume hole 23 fits on the outer surface of the sound and light alarm 2. When rain falls on the surface of the sound and light alarm 2, it will not enter the horn volume hole 23 but directly slide to the ground.

[0046] In this embodiment, the traveling mechanism 31 includes a column 313 , and a traveling device 311 and an anchoring device 312 respectively mounted on the land-side column 313A and the sea-side column 313B.

[0047] In this embodiment, the rotation mechanism 32 includes a turntable 322, a platform system 321, and a wheel clamp control cabinet 314 located on the side of the platform system 321. A cylindrical gantry 315 is installed on the side of the wheel clamp control cabinet 314. The rotation mechanism 32 uses the turntable 322 to realize the rotation of the portal crane 3. The wheel clamp control cabinet 314 is provided to suppress rotation after stopping operation. The platform system 321 is equipped with a cylindrical gantry 315 to assist operation.

[0048] In this embodiment, a balancing system 341 is provided adjacent to the luffing mechanism 34 to maintain the stability of the boom system 334. A load take-off device 342 is also provided adjacent to the balancing system 341 to facilitate lifting the boom system 334. The balancing system 341 and the boom system 334 in the luffing mechanism 34 are connected via a connecting column 343.

[0049] Specifically, the balancing system 341 and the load power take-off device 342 jointly adjust the amplitude of the boom system 334; the balancing system 341 is used to adjust the overall position of the boom system 334, and the load power take-off device 342 is used to enhance the force to assist in completing the adjustment work of the balancing system 341.

[0050] In this embodiment, the position change of the portal crane 3 is achieved by the relative movement of the traveling device 311 and the anchoring device 312 in the traveling mechanism 31 .

[0051] In this embodiment, the driver's cab 331 and the machine room 332 in the hoisting mechanism 33 operate the boom system 334 through the electrical system 333 to complete the operation of the portal crane 3.

[0052] Specifically, the boom system 334 lifts the sling 3343 through the lifting assembly 3341 to carry objects, and the lifting assembly 3341 and the sling 3343 are connected by a balance rope 3342.

[0053] The following content explains the working principle of this utility model:

[0054] When the gantry crane 3 starts to operate, the sound and light alarm 2 set on the gantry crane 3 through the bracket 1 also starts to work at the same time. The sound and light alarm 2 emits an alarm and lights up when it is operating. When it rains, since the sound and light alarm 2 is horizontally arranged through the vertical part 12 of the bracket 1, and the horn volume hole 23 of the sound and light alarm 2 is arranged at the bottom, when rain falls on the outer surface of the sound and light alarm 2, the rain directly drips along the outer surface of the sound and light alarm 2 to the ground due to the action of gravity, and does not enter the horn volume hole 23.

[0055] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
