Description

Technical Field

[0001] The invention relates to a garbage transfer vehicle body weighing device and a garbage transfer vehicle equipped with the weighing device. Background Art

[0002] Garbage transfer trucks have been widely used to transfer garbage from the middle end of the transfer, such as a transfer station, to the end end, such as an incineration plant, a landfill, etc. In order to facilitate the loading and unloading of garbage, the garbage transfer truck can be realized as a detachable body type, which uses a pulling arm device to lift and lower the body to complete the loading and unloading of garbage.

[0003] The current problem with garbage transfer trucks is that the weight of the garbage-loaded compartment is not known at the transfer station. Therefore, the entire process of the garbage transfer truck from the transfer station to the terminal incineration plant or landfill may be completed under overweight, which will cause the braking distance to become longer, thereby potentially increasing the driving risk of the garbage transfer truck.

[0004] At present, a scale is usually set up at the end of the transfer, such as an incinerator or landfill, to weigh the garbage transfer trucks arriving there. However, even if the transfer truck is overweight, its overweight travel from the transfer station to the end incinerator or landfill has become an established fact, so the potential dangers caused by overweight cannot be avoided.

[0005] Therefore, there is a need for a garbage transfer vehicle body weighing device and a garbage transfer vehicle equipped with the same. Summary of the invention

[0055] The preferred embodiments of the garbage transfer vehicle body weighing device and the garbage transfer vehicle equipped with the same according to the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that only the structure related to the body weighing function of the garbage transfer vehicle is described in detail below, and the description of other parts of the garbage transfer vehicle known to those skilled in the art is omitted.

[0056] It should be noted that the terms "first" and "second" appearing in this document may be used to distinguish any one element from another element. However, without departing from the technical spirit of the present disclosure, the first element and the second element may be arbitrarily named according to the convenience of those skilled in the art. The terms "front" and "rear" appearing in this document are referenced to the front and rear directions of the garbage transfer vehicle.

[0057] Figure 1The schematic diagram schematically shows the arrangement of the garbage transfer vehicle body weighing device according to the present invention on the arm device. The arm device 200 includes a first beam 210 and a second beam 220. The figure only shows the portion of the first beam 210 and the second beam 220 on which the garbage transfer vehicle body weighing device according to the present invention is arranged, and omits other portions known to those skilled in the art. In the existing garbage transfer vehicles, the upper surface of the arm device directly supports the body loaded with garbage to complete the loading and unloading of the body.

[0058] In order to avoid overloading of the garbage transfer vehicle from the transfer station to the terminal incineration plant or landfill, the garbage transfer vehicle body weighing device 100 proposed in the present invention includes a first weighing component 110 arranged on the arm device 200 near the front end of the body and a second weighing component 120 arranged on the arm device 200 near the rear end of the body. The first weighing component 110 and the second weighing component 120 each include at least one sensor 130, and the at least one sensor 130 is configured to obtain the weight of the body when the body is horizontally placed on the first weighing component 110 and the second weighing component 120. The weight can be calculated, for example, by the pressure applied by the body to the first weighing component 110 and the second weighing component 120 sensed by the at least one sensor 130.

[0059] like Figure 1 As shown, the first weighing assembly 110 may include a first front weighing device 111 and a second front weighing device 112 which are symmetrical to each other and respectively arranged on the first beam 210 of the arm pulling device 200, and the second weighing assembly 120 includes a first rear weighing device 121 and a second rear weighing device 122 which are symmetrical to each other and respectively arranged on the first beam 210 of the arm pulling device 200 and respectively arranged on the second beam 220 of the arm pulling device 200. That is, the garbage transfer vehicle body weighing device 100 according to the present invention may include four weighing devices arranged on the arm pulling device 200 and respectively contacting the four corner areas of the bottom of the body, wherein each weighing device may include at least one sensor 130 to sense the pressure applied by the body to each weighing device when in contact with the body. The four weighing devices arranged symmetrically in this way can make the weighing devices evenly stressed when in contact with the body, so that the sensors can accurately sense the pressure applied by the body to each weighing device, and then the accurate body weight can be calculated.

[0060] Figure 1It is shown that each weighing device is provided with a sensor 130, which is arranged to be at least partially located inside the first weighing assembly 110 and the second weighing assembly 120 and to contact the surface of the bottom of the carrying compartment of the first weighing assembly 110 and the second weighing assembly 120. This arrangement of the sensor 130 is advantageous. On the one hand, since the sensor 130 is in direct contact with the surface of the bottom of the carrying compartment of each weighing assembly, it is convenient for it to sense the pressure applied by the compartment to each weighing assembly. On the other hand, since the sensor 130 may require a higher sensing accuracy, the sensor 130 is arranged to be at least partially located inside each weighing assembly to avoid any bumps or movements that may occur during the driving of the garbage transfer vehicle, thereby further ensuring its high sensing accuracy.

[0061] However, the present invention is not limited to each weighing device being provided with only one sensor 130. For example, each weighing device may be provided with two or more sensors 130. Each sensor 130 may be, for example, a pressure sensor. In order to be applicable to weighing various garbage trucks with different load capacities, the sensor 130 may be selected as a pressure sensor with a wider measuring range, or a suitable number of pressure sensors with a suitable measuring range may be selected according to the different load capacities of the actual garbage trucks. When each weighing device is provided with two or more sensors 130, the pressure applied by the car body to the weighing device may be calculated as the average of the pressures sensed by the two or more sensors 130. Thus, the pressure applied by the car body to each weighing device may be obtained more accurately, and then a more accurate car body weight may be calculated.

[0062] Figure 1 The first front weighing device 111 and the second front weighing device 112 each include a first body 113, a first side plate 114, a first mounting assembly 115 and at least one sensor 130, while the first rear weighing device 121 and the second rear weighing device 122 each include a second body 123, a second side plate 124, a second mounting assembly 125, at least one sensor 130 and a roller assembly 127. Figure 2A and Figure 3A The specific construction and arrangement of these components are described in detail.

[0063] Figure 2A A schematic three-view diagram of a portion of the first weighing assembly 110 of the garbage transfer vehicle body weighing device 100 according to the present invention is shown. Specifically, this portion can constitute the first front weighing device 111 (if it is arranged on the first beam 210 of the arm-pulling device 200), and it can also constitute the second front weighing device 112 (if it is arranged on the second beam 220 of the arm-pulling device 200).

[0064] like Figure 2AAs shown, the first front weighing device 111 and the second front weighing device 112 each include a first body 113 , a first side plate 114 , a first mounting assembly 115 and at least one sensor 130 .

[0065] At least one sensor 130 is partially located inside the first body 113 of the first front weighing device 111 and the second front weighing device 112 and contacts the top surface of the first body 113, and is configured to sense the pressure applied to the first front weighing device 111 and the second front weighing device 112 by the vehicle body when the vehicle body is placed horizontally on the first body 113 of the first front weighing device 111 and the second front weighing device 112.

[0066] The first side plate 114 is attached to the first body 113, for example, to the outer side surface of the first body 113, that is, the surface away from the box. When the box is supported on the first beam 210 and the second beam 220 of the arm pulling device 200 and contacts the first front weighing device 111 and the second front weighing device 112, the box is stuck between the first side plates 114 of the first front weighing device 111 and the second front weighing device 112, so as to limit the displacement of the box in its width direction (left-right direction).

[0067] The first mounting assemblies 115 of the first and second front weighing devices 111 and 112 are used to mount the first bodies 113 of the first and second front weighing devices 111 and 112 to the first and second beams 210 and 220 of the arm-pulling device 200 .

[0068] Figure 2A It is schematically shown that each first mounting assembly 115 includes two substantially inverted "U"-shaped mounting plates, which are formed around the upper surface and parts of the two side surfaces of the first beam 210 or the second beam 220 of the arm pulling device 200. The first mounting assembly 115 also includes a fastening device, such as a bolt, etc., by means of which the mounting plate is fastened to the first beam 210 or the second beam 220 of the arm pulling device 200. Since the first beam 210 and the second beam 220 of the arm pulling device 200 may have non-planar upper surfaces, with the help of the two first mounting assemblies 115, it is possible to achieve that the respective first bodies 113 of the first front weighing device 111 and the second front weighing device 112 are firmly mounted to the first beam 210 and the second beam 220 of the arm pulling device 200.

[0069] Optionally, the first front weighing device 111 and the second front weighing device 112 each further include a first spacer plate 116 located between the corresponding first body 113 and the first mounting assembly 115, such as Figure 2B As shown, it shows Figure 2ADetail of area A in FIG. The first spacer plate 116 can be welded or otherwise fixed between the first body 113 and the first mounting assembly 115, for example. The first spacer plate 116 can be made to have a planar upper surface, so that when the car body is horizontally supported on the first beam 210 and the second beam 220 of the arm pulling device 200 and contacts the first front weighing device 111 and the second front weighing device 112, pressure is evenly applied to the first front weighing device 111 and the second front weighing device 112, so that the pressure sensed by the sensor 130 and the weight of the car body obtained are more accurate.

[0070] Figure 3A A schematic three-view diagram of a portion of the second weighing assembly 120 of the garbage transfer vehicle body weighing device according to the present invention is shown. Specifically, this portion can constitute the first rear weighing device 121 (if it is arranged on the first beam 210 of the arm pulling device 200), and it can also constitute the second rear weighing device 122 (if it is arranged on the second beam 220 of the arm pulling device 200).

[0071] like Figure 3A As shown, the first rear weighing device 121 and the second rear weighing device 122 each include a second body 123, a second side plate 124, a second mounting assembly 125, and a sensor 130. Optionally, the first rear weighing device 121 and the second rear weighing device 122 each further include a second spacer plate 126 having a planar upper surface and located between the corresponding second body 123 and the second mounting assembly 125, as shown in FIG. Figure 3B As shown, it shows Figure 3A Details of area B in .

[0072] The second body 123 , the second side plate 124 , the second mounting assembly 125 and the second partition plate 126 of the first rear weighing device 121 and the second rear weighing device 122 may have similar constructions and arrangements to the corresponding components of the first front weighing device 111 and the second front weighing device 112 , respectively, and thus their detailed descriptions are omitted herein.

[0073] Different from the first front weighing device 111 and the second front weighing device 112, the first rear weighing device 121 and the second rear weighing device 122 may respectively include a roller assembly 127 attached to the corresponding second body 123, such as Figure 3A When the car body is loaded and unloaded by means of the arm-pulling device 200 , the car body slides along the first beam 210 and the second beam 220 of the arm-pulling device 200 by means of the roller assembly 127 .

[0074] Specifically, see Figure 3AThe roller assembly 127 may include a first roller 128 and a second roller 129 respectively located at the front and rear sides of the second body 123 and attached to the second body 123, so that when the car body is carried on the first beam 210 and the second beam 220 of the arm pulling device 200, the bottom surface of the car body can contact the top surfaces of the first roller 128 and the second roller 129.

[0075] like Figure 3A As shown, the top surfaces of the first roller 128 and the second roller 129 are higher than the upper surface of the second body 123, so that during the loading and unloading process of the compartment, the compartment is completely supported on the first roller 128 and the second roller 129 of the respective roller assemblies 127 of the first rear weighing device 121 and the second rear weighing device 122, and can slide in the front and rear directions of the garbage transfer vehicle with the help of these rollers. Since the compartment loaded with garbage usually has a considerable weight, this sliding with the help of the roller assembly 127 can greatly reduce the friction force of the compartment during the loading and unloading process, thereby completing the loading and unloading of the compartment more smoothly. In addition, after the loading and unloading are completed, the compartment is horizontally supported on the first roller 128 and the second roller 129 of the respective roller assemblies 127 of the first rear weighing device 121 and the second rear weighing device 122, and the pressure is fully applied to the corresponding first roller 128 and the second roller 129.

[0076] At least one sensor 130 is partially located inside the first rear weighing device 121 and the second rear weighing device 122 and contacts the top surface of the corresponding roller assembly 127 of the first rear weighing device 121 and the second rear weighing device 122, and is configured to sense the pressure applied by the car body to the corresponding roller assembly 127 of the first rear weighing device 121 and the second rear weighing device 122 when the car body is placed horizontally on the first rear weighing device 121 and the second rear weighing device 122.

[0077] It should be noted that although Figure 3A The roller assemblies 127 of the first rear weighing device 121 and the second rear weighing device 122 are shown to each have two rollers 128 and 129, but the present invention is not limited thereto. For example, the roller assembly 127 may include two or more first rollers 128 and two or more second rollers 129, respectively located at the front and rear sides of the second body 123 and attached to the second body 123, thereby satisfying the smooth loading and unloading of the transfer vehicle body with different load capacities. In this case, at least one sensor 130 is configured to sense the sum of the pressures applied by the body to the two or more first rollers 128 and the two or more second rollers 129.

[0078] The present invention also provides a garbage transfer vehicle having a vehicle body weighing device according to the present invention. Figure 4A schematic block diagram of the parts of the garbage transfer vehicle 300 according to the present invention related to the vehicle weighing function is shown. The garbage transfer vehicle 300 according to the present invention includes:

[0079] The aforementioned compartment weighing device 100;

[0080] a processing unit 310, which is in communication connection with the first weighing assembly 110 and the second weighing assembly 120 of the car body weighing device 100, that is, in communication connection with each weighing device 111, 112, 121 and 122, so as to receive the pressure exerted by the car body sensed by at least one sensor 130 of each weighing device 111, 112, 121 and 122 when the car body is horizontally placed on the first weighing assembly 110 and the second weighing assembly 120, thereby calculating the weight of the car body; and

[0081] The display unit 320 is communicatively connected to the processing unit 310 and is configured to display the weight of the vehicle body calculated by the processing unit 310 .

[0082] The processing unit 310 may be arranged, for example, on the chassis of the garbage transfer vehicle 300 or the aforementioned arm device 200, and the display unit 320 may be arranged, for example, on the cab of the garbage transfer vehicle 300 so that the driver can know the weight of the vehicle body. However, the arrangement positions of the processing unit 310 and the display unit 320 are not limited thereto.

[0083] Optionally, the garbage transfer vehicle 300 may further include an alarm unit 330, which is connected to the display unit 320 in communication. When the weight of the vehicle displayed on the display unit 320 exceeds its nominal load, the alarm unit 330 is triggered to send an alarm signal to remind the driver that the current garbage transfer vehicle is at risk of being overweight. Alternatively, the alarm unit 330 may also be connected to the processing unit 310 in communication. When the weight of the vehicle calculated by the processing unit 310 exceeds its nominal load, the alarm unit 330 is triggered to send an alarm signal. The alarm unit 330 may be arranged at the cab of the garbage transfer vehicle 300, for example, and the alarm signal it sends may be in the form of sound or light, etc., but the present invention is not limited thereto.

[0084] When the driver receives the alarm signal, he can be informed in time that the current garbage transfer vehicle 300 is in an overweight state. Since the garbage transfer vehicle 300 is still at the transfer station at this time, the driver can properly unload a part of the garbage in the vehicle body, so that the vehicle body weight calculated by the processing unit 310 or displayed by the display unit 320 drops below the nominal load of the garbage transfer vehicle 300, so that the alarm unit 330 will no longer be triggered to send an alarm signal. This ensures that the garbage transfer vehicle will be in a normal load state during the entire process of leaving the transfer station and driving to the terminal incineration plant or landfill, thereby avoiding the risk of overweight driving.

[0085] Optionally, the garbage transfer vehicle 300 may further include a printing unit 340, which is communicatively connected to the display unit 320 and is configured to print the weight of the vehicle displayed at the display unit 320. Further, the printing unit may be configured to print out the price of the loaded garbage corresponding to the weight of the vehicle. Thereby, if the garbage loaded by the garbage transfer vehicle 300 is intended to be recycled, when the garbage transfer vehicle 300 completes loading at the transfer station, the driver can promptly evaluate and record the price of the currently loaded garbage. Similarly, the printing unit may be arranged, for example, at the cab of the garbage transfer vehicle 300.

[0086] The following summarizes the process of weighing the compartment of the garbage transfer vehicle 300 according to the present invention:

[0087] At the transfer station, the garbage transfer vehicle 300 loads the garbage into the compartment with the aid of the arm pulling device 200;

[0088] When the compartment is horizontally placed on the first weighing assembly 110 and the second weighing assembly 120 of the weighing device 100 according to the present invention, the respective sensors 130 provided on the first weighing assembly 110 and the second weighing assembly 120 sense the pressure applied by the compartment;

[0089] The processing unit 310 receives the sensing results of each sensor 130 and calculates the weight of the vehicle body based on the sensing results;

[0090] The processing unit 310 sends the weight of the car body to the display unit 320, and the display unit 320 displays the weight of the car body;

[0091] When the weight of the compartment calculated by the processing unit 310 or displayed by the display unit 320 exceeds the nominal load capacity of the garbage transfer vehicle 300, the alarm unit 330 is triggered to send out an alarm signal;

[0092] When the driver receives the alarm signal, he unloads part of the garbage in the compartment and re-weighs the compartment until the alarm unit 330 no longer issues an alarm signal;

[0093] The printing unit 340 prints the weight of the garbage transfer vehicle 300 and optionally prints the price of the loaded garbage corresponding to the weight of the vehicle;

[0094] On the premise of ensuring that the weight of the vehicle body does not exceed the nominal load capacity of the garbage transfer vehicle 300, the garbage transfer vehicle 300 leaves the transfer station and drives to the terminal incineration plant or landfill plant in a normal load state.

[0095] The above describes in detail a feasible but non-limiting implementation of the garbage transfer vehicle body weighing device according to the present invention and the garbage transfer vehicle equipped with the same with the aid of the accompanying drawings. For ordinary technicians in this field, without departing from the scope and essence of the present disclosure as set forth in the following claims, modifications and supplements to the technology and structure and the re-combination of the features in the embodiments should obviously be regarded as included in the scope of the present invention. Therefore, these modifications and supplements that can be conceived under the teachings of the present invention should be regarded as part of the present disclosure.
