Description

Technical Field

[0001] This utility model belongs to the field of isolation and protection technology for coal mine electromechanical equipment, and particularly relates to an isolation and protection device for coal mine electromechanical equipment. Background Technology

[0002] In coal mining, a large number of electromechanical equipment are required. The most common electromechanical equipment includes large water pumps, motors, and corresponding electrical control cabinets, all of which are fixedly installed in specific locations within the roadway. To prevent operators from accidentally touching the electrical equipment and causing electric shock hazards, existing technologies involve installing guardrails around the electromechanical equipment.

[0003] The main structure of the guardrail includes a support frame and a mesh screen fixed to the support frame. The support frame and the mesh screen form a dike structure to protect the electromechanical equipment from the outside. Guardrail gates are also installed on the guardrail to allow people and objects to enter and exit.

[0004] The guardrails not only protect workers, but also isolate mechanical and electrical equipment from the complex environment of the tunnel, preventing flying rocks, debris, and other debris from hitting the equipment and causing damage.

[0005] However, in actual operation, the protective fence only surrounds the equipment from all sides, leaving the top of the equipment exposed. In traditional environments, such as factories and workshops, this type of fence can indeed provide effective isolation and protection.

[0006] The environment of coal mining roadways is different because there is often a risk of falling rocks from the top of the roadway. Although the existing technology supports the top of the roadway through roof support, firstly, roof support cannot be without blind spots. Instead, it is supported at certain intervals. The reason is that interval support can effectively prevent the roadway from collapsing and large pieces of gravel from falling from the top of the roadway.

[0007] However, in actual operation, rock fragments and dust still fall from the tunnel roof (from between the support plates and at the edges of the support plates), causing severe lining buildup on the equipment and significant damage to equipment and personnel from falling rock fragments. Especially when large equipment is operating, such as fully mechanized mining equipment, the vibration within the tunnel increases, and falling rocks impacting electrical equipment can easily cause malfunctions. For example, falling rocks impacting the drive shaft of the power equipment motor can also pose a potential danger to the equipment operators. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide an isolation and protection device for coal mine electromechanical equipment.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An isolation and protection device for coal mine electromechanical equipment includes a guardrail mechanism that blocks the perimeter of the electromechanical equipment; it also includes a top cover mechanism that covers the top of the guardrail mechanism.

[0011] The top cover mechanism includes a steel structure support installed at the top of the guardrail mechanism, and a protective plate is laid on the steel structure support;

[0012] The edge of the protective plate is fixedly connected with a barrier structure to prevent falling rocks from sliding down;

[0013] It also includes a rockfall guide structure installed on the barrier structure.

[0014] Preferably, the guardrail mechanism includes a plurality of upright posts for setting up a cofferdam, and a retaining net is fixedly connected between the upright posts;

[0015] It also includes hinged gates for people and objects to pass through.

[0016] Preferably, the steel structure support includes transverse beam structures that are detachably installed on both sides of the top of the guardrail mechanism;

[0017] The transverse beam structure includes a first span beam and a second span beam symmetrically arranged on both sides;

[0018] One end of the first span beam and one end of the second span beam are detachably installed on it, and a horizontal support beam is detachably installed between the other ends of the first span beam and the second span beam.

[0019] Preferably, the lower ends of the first span beam and the second span beam are respectively welded with first mounting seats, and the top of the column rod is welded with matching mounting seats. The first mounting seats and the second mounting seats are connected by bolt assembly.

[0020] The upper ends of the first span beam and the second span beam are welded with third mounting seats, and the side walls on both sides of the horizontal support beam are respectively welded with fourth mounting seats. The third mounting seats and the fourth mounting seats are connected by bolts.

[0021] Preferably, both the first span beam and the second span beam include inclined beam portions that support the protective plate, with the inclined beam portions tilted upwards.

[0022] The protective plate includes sloping sections supported on both sides of the inclined beams, and the sloping sections are integrally formed with horizontal sections, which are supported on horizontal support beams.

[0023] Preferably, a plurality of supporting purlins are installed between the inclined beams, and the supporting purlins are supported at the bottom of the slope.

[0024] Preferably, the baffle structure includes a baffle plate fixedly connected to the top edge of the protective plate;

[0025] The baffle plate includes an arc-shaped baffle plate portion that matches the shape of the crossbeam structure, and a partition baffle plate portion is integrally formed between the arc-shaped baffle plate portions.

[0026] Preferably, the partition grid plate has a slag discharge port, and a slag guide cylinder is welded and fixedly connected to the slag discharge port.

[0027] Preferably, the protective plate is made of acrylic material.

[0028] This utility model has the following beneficial effects:

[0029] 1. The present invention solves the technical defects of falling gravel, stone chips, and dust from the top of the roadway through the top cover mechanism. In particular, when large operating equipment is working, the vibration of the roadway ore layer structure exacerbates the impact damage of falling gravel, stone chips, and dust on the working equipment, affecting the safe operation of the equipment and causing potential impact injuries to the equipment operators.

[0030] 2. In the actual operation, when rocks, gravel, or dust fall, the rocks directly impact the protective plate and slide down the slope of the plate to the outside of the entire guardrail mechanism. This method protects the equipment.

An integral baffle baffle plate part is formed between the arched baffle plate parts. A slag discharge port is opened on the baffle baffle plate part. A slag guide cylinder is welded and fixedly connected to the slag discharge port. The falling rocks fall into the slag discharge port. Attached Figure Description

[0044] Example 1

[0045] like Figure 1-7As shown, a protective device for mine machinery and equipment includes a protective barrier mechanism 1, identical to existing protective barrier mechanisms 1, which forms a perimeter around the working machinery and equipment. Specifically, the protective barrier mechanism 1 includes several columns 12 arranged around the perimeter (i.e., the columns 12 surround the equipment), with a mesh 11 fixedly connected between the columns 12. The columns 12 and the mesh 11 form a rectangular protective barrier structure. Similar to existing protective barriers that open and close to allow people and objects to enter and exit, the protective barrier mechanism 1 also includes a hinged gate 2 for passage. Specifically, the gate 2 is identical to existing structures, including a gate frame and a metal mesh fixed within the gate frame. One side of the guardrail frame is hinged to the upright post 12 on the left side, and the other side is installed on the upright post 12 on the right side by a conventional fixing method such as a pin (not shown in the figure) (that is, a pin is slidably connected to the upright post 12, corresponding to a fixed sleeve on the guardrail frame, so as to realize the insertion and removal). When opening the guardrail, the pin is pulled out and the guardrail is flipped open.

[0046] To prevent the falling of gravel, stone chips, and dust from the top of the tunnel, especially during the operation of large equipment, which can cause vibrations in the mine structure and exacerbate impact damage to the equipment, thus affecting its safe operation and posing a potential risk of fall injury to operators, this utility model proposes the following improvements:

[0047] It also includes a top cover mechanism that covers the top of the guardrail mechanism 1; the top cover mechanism covers the top of the guardrail mechanism 1 to prevent gravel, stone chips and dust from falling.

[0048] Specifically, the top cover mechanism includes a steel structure support 4 installed at the top of the guardrail mechanism 1, and a protective plate 5 is laid on the steel structure support 4; a barrier structure 3 for preventing falling rocks from sliding is fixedly connected to the edge of the protective plate 5.

[0049] It also includes a rockfall guide structure installed on the barrier structure 3.

[0050] During operation, if gravel, stone chips, or dust fall, they will directly impact the protective plate. The protective plate effectively prevents the gravel, stone chips, and dust from causing injury to the equipment and personnel.

[0051] Example 2

[0052] like Figure 1-7 As shown, based on the structure of Embodiment 1, the steel structure support 4 includes a crossbeam structure 4 that can be detachably installed on the front and rear sides of the top of the guardrail mechanism 1.

[0053] That is, a crossbeam structure 4 spans between the two uprights 12 on the front side, and a crossbeam structure 4 spans between the two uprights 12 on the rear side.

[0054] The specific structure of the transverse beam structure 4 is as follows: the transverse beam structure 4 includes a first span beam 41 and a second span beam 42 symmetrically arranged on the left and right sides.

[0055] One end (lower end) of the first span beam 41 and the second span beam 42 can be detachably installed on the column rod 12. Specifically, the lower ends of the first span beam 41 and the second span beam 42 are respectively welded with a first mounting seat A, and the top of the column rod 12 is welded with a matching mounting seat. The first mounting seat and the second mounting seat are connected by bolt assembly.

[0056] The purpose of achieving detachable installation through the above structure is to allow for the following: during the construction of the guardrail structure, the existing guardrail mechanism 1 cofferdam is installed first, and then the first span beam 41 and the second span beam 42 are directly assembled and installed onto the column pole 12. This method reduces the difficulty of installation.

[0057] Meanwhile, in order to improve the structural strength of the steel structure and increase the support strength of the protective plate, a horizontal bracing beam 43 is detachably installed between the other ends of the first span beam 41 and the second span beam 42.

[0058] Specifically, the upper ends of the first span beam 41 and the second span beam 42 are welded with third mounting seats, and the side walls on both sides of the horizontal support beam 43 are respectively welded with fourth mounting seats. The third mounting seats and the fourth mounting seats are connected by bolts.

[0059] The first span beam 41 and the second span beam 42 are both shaped as follows: they include inclined beams that support the protective plate, and the inclined beams are inclined upwards; correspondingly, the protective plate 5 includes sloping sections that are supported on the inclined beams on both sides, and the sloping sections are integrally formed with horizontal sections that are supported on horizontal support beams 43.

[0060] During operation, when rocks, gravel, and dust fall, the rocks directly impact the protective plate 5 and slide down its sloping structure to the outside of the entire guardrail mechanism 1. This method protects the equipment.

[0061] In actual operation, protective plate 5 uses reinforced acrylic material, such as acrylic sheets with a honeycomb structure, to reduce its weight and facilitate installation. Similarly, the first span beam 41 and the second span beam 42 can be made of aluminum alloy steel. This lightweight structural design increases the ease of installation. Furthermore, although there are falling rocks at the top of the tunnel, large falling rocks can be prevented by the tunnel's roof support. Therefore, the lightweight steel structure and protective plate 5 effectively protect equipment and personnel from small pieces of gravel, debris, and falling dust.

[0062] Therefore, the protective plate 5, the first span beam 41, and the second span beam 42 with the above-mentioned structure and materials not only reduce the difficulty of installation and the load on the guardrail mechanism, but also have a lower economic cost.

[0063] Example 3

[0064] like Figure 1-7 As shown, this embodiment is based on the structure of embodiment 2. In order to further increase the support for the protective plate 5, several supporting purlins are installed between the inclined beams. Specifically, through holes are opened on the inclined beams of the first span beam 41 and the second span beam 42 at both ends. After the supporting purlins are passed through the through holes, they are supported on the bottom of the protective plate 5. In actual operation, the supporting purlins can be fastened to the first span beam 41 and the second span beam 42 with bolts from both ends.

[0065] Similarly, the aforementioned protective plate 5 can be fastened to the first span beam 41, the second span beam 42, and the horizontal support beam 43 by bolting in the existing manner.

[0066] Example 4

[0067] like Figure 1-7 As shown, this embodiment, based on the structure of embodiment 3, aims to facilitate the cleaning of rocks that fall onto the protective plate 5 and prevent rocks from rolling off the protective plate 5 in a disorderly manner. The aforementioned baffle structure 3 includes a baffle plate fixedly connected to the top edge of the protective plate 5; the baffle plate forms a dam at the top edge of the protective plate 5.

[0068] The baffle plate includes an arc-shaped baffle plate portion 31 that matches the shape of the crossbeam structure 4, and an integral baffle baffle plate portion 32 (located at the edge of the slope of the protective plate 5) is formed between the arc-shaped baffle plate portions 31.

[0069] Meanwhile, a slag discharge port is provided on the baffle plate 32, and a slag guide cylinder 33 (formed as a cuboid) is welded and fixedly connected to the slag discharge port.

[0070] Rocks fall into the slag discharge port and slide down the slag guide cylinder 33 in a specific direction. In actual operation, the rockfall area is located on both sides of the guardrail mechanism 1. Therefore, in order to further increase safety, a fence can be set up in the rockfall area.

[0071] In actual operation, the guide slag cylinder 33 can also be designed as a downward structure, with the discharge end of the guide slag cylinder 33 close to the ground, to further increase the safety of the falling rock cone.

[0072] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
